Once upon a time there was a computer music system called GROOVE (Generating Realtime Operations On Voltage-controlled Equipment, Bell Telephone Laboratories, Murray Hill, New Jersey) which outputted in the realm of sound, and was a wonderful and still-unique tool for the composition thereof. At that time a then-young composer who was using GROOVE for music got the harebrained idea that if she made a few minor changes here and there she could use it to compose images as well. This she did in 1974-6, and though the untimely demise of the system prevented creation of much documentation in the form of aesthetic works of its output, the system did function sufficiently to make some description worthwhile. While it is true that the mid-1960s DDP-224 computer on which GROOVE became a VAMPIRE (Video And Music Program for Interactive Realtime Exploration/Experimentation) was a massive room-sized computer, it has by now long been eclipsed in power by the constantly improving home computer. It is worth describing the concepts involved in part because there are by now many small computers capable of emulating its musical methods. Besides, I had a deep personal relationship with that computer, and wish to commemorate it. Here then follows the tale of Graphical GROOVE, aka the VAMPIRE.

Interactive computer music is comparable to improvisation because it includes elements of real-time composition performed by the computer. This process of real-time composition often incorporates stochastic techniques that remap a predetermined fundamental structure to a surface of sound processing. The hierarchical structure is used to pose restrictions on the stochastic processes, but, in most cases, the hierarchical structure in itself is not created in real time. This article describes how existing musical analysis methods can be converted into generative compositional tools that allow composers to generate musical structures in real time. It proposes a compositional method based on generative grammars derived from Pierre Schaeffer's TARTYP, and describes the development of a compositional tool for real-time generation of Klumpenhouwer networks. The approach is based on the intersection of musical ideas with fundamental concepts in computer science including generative grammars, predicate logic, concepts of structural representation, and various methods of categorization.

A computer-assisted composition tool for investigating the application of evolutionary techniques in the composition of music is presented. The nature of such an application is examined in terms of defining the possible mechanisms that provide a means for automated creativity. These mechanisms take inspiration from processes found in Darwinian-based evolution theory, genetic algorithm theory and similar aesthetically based uses of a genetic search heuristic in the visual arts. A formal model of ‘musical evolution’ is proposed, with particular emphasis placed on the ways in which a genetic algorithm can be used to effectively manipulate a variety of compositional structures within a hierarchical and generative grammar-based model of musical composition. The result is a prototype Windows MIDI application called GeNotator that allows composers to experiment with a range of musical structures by interactively ‘evolving’ them through a familiar and comprehensive graphical user interface.

This article deals with a way that algorithmic composition systems can be informed by material realities of musical performance. After a general discussion of the relation of abstract algorithms to concrete materiality, the article focuses on the idea of an instrument's space of possibilities. It briefly discusses a number of compositional approaches that seek to derive musical structure from bodily movements and from the physical properties of instruments. The last part describes a new open-source JavaScript library called OboeJS and a Web application based on this library. The system is an experimental exploration of the idea of instrumental space and an attempt to bring together abstract algorithmic processing and the concrete possibilities of a musical instrument. The system implements a flexible constraint-based search algorithm for the generation of oboe fingering sequences. This tool is presented as part of a wider approach to algorithmic composition that aims not to map data output of generative procedures to “sound generators” (e.g., performers, instruments, sound synthesis processes). Instead, I propose to derive structure from the space of possibilities of the instrument itself, which in this case is the oboe.

Nowadays, computers are extremely beneficial to music composers. Computer music generation tools are developed for aiding composers in producing satisfying musical pieces. The automation of music composition tasks is a challenging research point, specially to the field of Artificial Intelligence. Converting melodies that are played on a major scale to minor (or vice versa) is interesting to both composers and music listeners. Newly converted melodies of famous songs, either from major to minor or the opposite, are becoming blockbusters on the social media. In this paper we propose an intelligent method for automating the conversion between major and minor melodies using Artificial Intelligence techniques. We run our experiments on melodies in the MIDI format which is a standard music format enabling the communication between computers and various musical devices. We also propose a smart method for musical scale detection for the input melodies. Scale detection is a critical step for correctly converting between major and minor melodies. Additionally, this step is also important as a pre-processing step in various other music retrieval or transformation applications.

AbstractLarge-scale polyrhythms appear in almost every composition Elliott Carter wrote during the 1980s. The roots of this technique can be found in earlier compositions where Carter deliberately combined different simultaneous speeds not only at the musical surface, but also at a deeper, structural level. In A Mirror on which to dwell (1975), he already uses this compositional tool as a form-generating feature. Through the analysis of three songs from this cycle (Anaphora, Insomnia and O Breath), it is shown how the appearance of structural polyrhythms at the musical surface is meticulously organized through pitch organization, instrumentation and the relation with text. The double function of the polyrhythm – as a surface phenomenon and a background structure – is essential for the understanding of this composition. It also shows the difference with Carter's later use of the same technique in the 1980s, where large-scale or structural polyrhythms are more of a constructional nature and remain invisible in the musical score.

Experienced musicians have the ability to understand the structural elements of music compositions. Such an ability is built over time through the study of music theory, the understanding of rules that guide the composition of music, and countless hours of practice. The learning process is hard, especially for classical music, where the rigidity of the music structures and styles requires great effort to understand, assimilate, and then master the learned notions. In particular, we focused our attention on a specific type of music compositions, namely, music in chorale style (four-voice music). Composing such type of music is often perceived as a difficult task because of the rules the composer has to adhere to. In this article, we propose a visualization technique that can help people lacking a strong knowledge of music theory. The technique exploits graphic elements to draw the attention on the possible errors in the composition. We then developed an interactive system, named VisualMelody, that employs the proposed visualization technique to facilitate the understanding of the structure of music compositions. The aim is to allow people to make four-voice music composition in a quick and effective way, that is, avoiding errors, as dictated by classical music theory rules. We have involved 40 people in testing VisualMelody in order to analyze its effectiveness, its usability, and the overall user satisfaction. We partitioned the people involved in the evaluation study into two groups evenly splitting the musical expertise. Then, we had one group use VisualMelody without the visualization facilities and the other using the tool enhanced with our visualization. On average, people in the group that used our visualization were 60% faster and produced music with less errors.

This article presents the results of collaboration between a composer and researchers in the context of vocal roughness and composing for voice. Our research focused on parametric control of distortion. Specifically, we present a software device that supports the manipulation and control of vocal roughness in real time, using a method based on amplitude modulation and filtering. The compositional interest in working with classically trained opera singers and with vocal distortion led us to initiate research in the signal-processing domain. Our goal was to develop a tool that could facilitate the production of distorted sounds without direct effort on the part of the singer. In this way, the singer can perform a nondistorted or lightly distorted sound, and the software tool will generate or magnify the distortion in real time.

AbstractWe discuss John Locke's ideas in his essay of 1690 on sound and its cognition and relation to bodily motion. The ideas have interesting implications for the construction of organised sound. We argue that our ecological and statistical experience of sounds in our natural (and man-made) environment is in several respects critical for our choices as soundsmiths and our impressions as listeners. Sonic repetition, both sensory and imag(in)ed, contributes to that environment. Input sounds may be ‘coupled’ to output sounds; and in some cases the physical processes generating sound and the cognitive processes of receiving them are joined. As music technologists we may think of the computer, our sonic vehicle, as a joined bodily sonic-prosthesis. ‘Simple’ sonic ideas may associate with each other through shared biological bases, and become tools for creation of ‘complex’ ideas, as Locke cogitates. Furthermore, we now have new routes towards such complex sounds, including our computer prostheses.

Abstract Paweł Hendrich’s compositions can be compared to macrocrystals - solids composed of numerous small and identical elements, constructed in accordance with a strict pattern. Importantly, the same internal crystal structure can produce forms highly diversified with regard to external shape. Similarly, this composer’s works are very precisely structured already on the level of individual sounds, but this structure is only a tool for the creation of very clear musical macroforms. The idea of emergence - of new values resulting from the combination of simple elements - is of key importance to this composer. The paper presents the principles of organising music material in the works of Paweł Hendrich. These are, among others: periodicity, multilayered structures, permutations and flexibility. These ideas are reflected in the musical work in many dimensions, both on the level of microand macro-structure. Their application exerts a major impact on the forms created by the composer. With the development of his musical language, the composer transforms his initial material more and more radically. Simple elements and processes that underlie the construction of his works become progressively more and more difficult to reconstruct, largely due to the application of a computer in the composition process. A comprehensive look at Paweł Hendrich’s entire output of compositions proves that his work is emergent as a whole. With each new piece, a new element is added, but all of them form a coherent system. No wonder, then, that one of the composer’s works bears the telling title of Emergon.

This article collates results from a number of applications of interactive evolution as a sound designer's tool for exploring the parameter spaces of synthesis algorithms. Experiments consider reverberation algorithms, wavetable synthesis, synthesis of percussive sounds and an analytical solution of the stiff string. These projects share the property of being difficult to probe by trial and error sampling of the parameter space. Interactive evolution formed the guidance principle for what quickly proved a more effective search through the multitude of parameter settings.The research was supported by building an interactive genetic algorithm library in the audio programming language SuperCollider. This library provided reusable code for the user interfaces and the underlying genetic algorithm itself, whilst preserving enough generality to support the framework of each individual investigation.Whilst there is nothing new in the use of genetic algorithms in sound synthesis tasks, the experiments conducted here investigate new applications such as reverb design and an analytical stiff string model not previously encountered in the literature. Further, the focus of this work is now shifting more into algorithmic composition research, where the generative algorithms are less clear-cut than those of these experiments. Lessons learned from the deployment of interactive evolution in sound design problems are very useful as a reference for the extension of the problem set.

This article is an interview with Victor Ulyanich — composer, Honored Artist of Russia, founder of the Computer Music Department of the Gnesins Russian Academy of Music, Professor, Ph.D. in History of Arts. The interview preceded by a brief characteristic of the composer's creativity, genre preferences and characterological content of his compositions, including nature and its sacredness, cosmos and human within it, correlations of all things in the Universe, temptation and resistance to it, and Christian ideas. The main attention is focused on a number of aspects of the Ladozvonn integrated musictheoretical system, which was created by the composer. In order to fully reveal the parameters of its functioning, the author conducted an interview with the composer, which fits seamlessly into the outline of the article. In the process of the dialogue, important points were revealed concerning the use of the main tool of the Ladozvonn system — colored rectangular matrices, the concepts of invariance and fractality, and timbre dramaturgy as a functional analogue of the system in harmony. During the dialogue with the musician, the author substantiates the need to introduce such special terms as "ladozvonn" and "ladozvonn tree" into compositional and musicological usage, as well as to refer not to mathematical, but to musical categories in the process of working on a computer work. The composer raises questions about the repertoire of computer music, and in conclusion, expresses an opinion on the state of modern culture and the composer's place in the world.

This article introduces an open-source Java-based programming environment for creative coding of agglomerative systems using Internet-of-Things (IoT) technologies. Our software originally focused on digital signal processing of audio—including synthesis, sampling, granular sample playback, and a suite of basic effects—but composers now use it to interface with sensors and peripherals through general-purpose input/output and external networked systems. This article examines and addresses the strategies required to integrate novel embedded musical interfaces and creative coding paradigms through an IoT infrastructure. These include: the use of advanced tooling features of a professional integrated development environment as a composition or performance interface rather than just as a compiler; techniques to create media works using features such as autodetection of sensors; seamless and serverless communication among devices on the network; and uploading, updating, and running of new compositions to the device without interruption. Furthermore, we examined the difficulties many novice programmers experience when learning to write code, and we developed strategies to address these difficulties without restricting the potential available in the coding environment. We also examined and developed methods to monitor and debug devices over the network, allowing artists and programmers to set and retrieve current variable values to or from these devices during the performance and composition stages. Finally, we describe three types of art work that demonstrate how the software, called HappyBrackets, is being used in live-coding and dance performances, in interactive sound installations, and as an advanced composition and performance tool for multimedia works.

Summary Horizontal well targeting is often a greater challenge in massive, fractured carbonates than in low-productivity, poorly connected, and relatively thin reservoirs. This paper discusses methods to target horizontal wellbores in three-dimensional space to both confirm the fracture interpretation and establish high-efficiency oil capture. Several well examples are presented to illustrate the targeting objectives and the resulting well performance. Early in the program, the horizontal drilling objectives sought to maximize the lateral length in a direction determined by offset well productivity; the sample philosophy as is used in matrix-dominated reservoirs. Analysis of these results and employment of methods presented in this paper indicate profit can be maximized by drilling to a specific target to intersect a fracture trend at an optimum elevation instead of concentrating on maximizing length of lateral. Intervals of rapid penetration, lost circulation, and/or bit slides, along with cutting sample compositions, provided insight for confirmation and extension of the fracture network interpretation. The width of disturbance and degree of fracturing observed along interpreted fracture trends are valuable data for improved fracture network interpretation and computer simulation. Both the elevation and number of fracture branches encountered are significant strategic planning issues for oil recovery from unconfined oil columns in a massive carbonate system. Results from a large number of horizontals indicate significant productivity increases are achieved by proper targeting of laterals into major fracture features. Introduction Horizontal wells provide a unique assessment tool for formations containing reservoirs dominated by discontinuous flow features such as fractures or interbedded sandstones. Massive carbonate formations are the most extreme setting for large-scale, high-contrast, discontinuous reservoir properties. In sandstones of moderate to low quality, horizontals are typically applied to improve rate by exposing additional formation for fluid entry at high drawdown. In carbonates, horizontals serve to intersect high-conductivity flow features. In sandstones, high flow quality often coincides with sand accumulation. In contrast, carbonate flow is often highly discontinuous while storage capacity remains a relatively continuous function (as limited by depositional and diagenetic porosity history). Since 1993, significant study has gone into identifying the extent and quality of fracture networks and the impact these systems have had on reservoir management, fluid reinjection, and completion efficiency.1,2 In west Texas alone, well over 100 short-radius horizontal wells have been drilled in one field since 1986. Horizontals drilled in this fractured carbonate reservoir were initially done to maximize oil production while limiting gas coning.3 With the recent fracture studies, emphasis has moved to using horizontal boreholes to connect with large flow features not penetrated in existing wellbores.4,5 These more recent wells have targeted fracture zones interpreted from flexure maps which are developed from a second derivative analysis of structural surface maps. This paper provides results of several horizontal wells drilled with the intent of cutting the interpreted fracture zones. Targeting horizontal wells requires an understanding of massive carbonate features as well as discontinuous flow features. This paper will discuss how mapping was used to determine flow-feature locations; how horizontal drilling techniques were used to intersect these targeted flow features; and a discussion of the refinement of the interpretation and the drilling operations. Massive Carbonate Flow Features What is a massive carbonate? Carbonates that have relatively thick (100 ft or greater) intervals of mixed porous and tight/brittle rock types, free of continuous soft shale or anhydrite layers, are considered massive for this discussion. Structural deformation is subtle in many massive carbonate reservoirs, but still highly significant in generating preferential flow within the reservoir body. Minor deformation, as resulting from differential compaction and formation dip growth is accommodated in a range of extensional fracturing of the relatively brittle carbonates. Potential solution enhancement of fracture and fault zones further enhances flow. The highly conductive flow features of these carbonates often are a mix of bedding parallel (matrix) and subvertical (fracture) features.2 Data gathered from vertical wells can bias the interpretation of flow-feature population due to sampling a greater population of bedding parallel features. Vertical wells statistically encounter numerous short, mostly random-oriented fractures, but very few of the largest subvertical fracture features. Horizontal wells, in contrast, encounter few bedding parallel flow features in exchange for a full range of subvertical fracture flow features. Horizontal wells can provide data for direct assessment of fracture frequency and matrix block size in contrast to the highly interpretive approach required for assessment from vertical well data. More importantly, horizontal well data provides insight into the lateral variance in subvertical fracture features. Significant variation is expected between low fracture intensity near the center of a large formation block relative to the high frequency expected near the edges of this block where strain is concentrated. Block edges for large-scale features may follow obvious faults, hingelines (linear trends of dip change), or structural noses. Fig. 1 conceptually illustrates a fractured rock mass with a horizontal well intersecting a strain zone of likely high-flow capacity. Often, the structural indications of block-edge strain zones are subtle and easily merged with interpreted depositional or erosional changes across the field. Here, horizontal well data are critical to generation of an adequate flow-feature model.

Since the mid-1980s, there has been a movement away from knowledge supplied by the teacher and towards talking, reflecting and explaining as ways to learn. An example of this change in focus is provided by the self-explanation work of Chi et al (1994) who describe an approach to talking science rather than hearing science. According to Chi and coworkers, generating explanations to oneself (self-explanations) facilitates the integration of new information into existing knowledge. Reflecting about one's own learning is the same as thinking about learning or metacognition. Metacognition can be defined as the understanding of knowledge, an understanding that can be reflected in either effective use or overt description of the knowledge in question (Brown, 1987). This definition of metacognition requires of a learner both internalized thinking about learning (that is, reflection), and externalized communication, through language or action, that indicates an understanding of knowledge (that is, a self-explanation). In the work described in this paper the overall pedagogical goal is to encourage creative reflection in learners. Creative reflection is defined as the ability of a learner to imagine musical opportunities in novel situations, and then to make accurate predictions (verbally) about these opportunities. To succeed at creative reflection there should be a correspondence between what a learner predicts will happen and what actually happens. An example would be a learner first writing a musical phrase using musical notation, then predicting verbally how that phrase will sound, playing the phrase back on a piano, and finally evaluating if the prediction was accurate or not. Very little work has been done on how computers can be used to support talking, reflecting and explaining in the creative subject-area of musical composition. The rest of this paper addresses this issue.DOI:10.1080/0968776980060115

Introduction Generative algorithms have been used for many years by computer musicians like Iannis Xenakis (Xenakis) and David Cope (Cope) to make complex electronic music composition. Advances in computer technology have made it possible to design music algorithms based upon specific pitch, timbre and rhythmic qualities that can be manipulated in real time with a simple interface that a child can control.jam2jam (Brown, Sorensen, & Dillon) is a shareware program developed in java that uses these ideas and involves what we have called Networked Improvisation, which ‘can be broadly described as collaborative music making over a computer network’ (Dillon & Brown). Fig. 1: jam2jam interface (download a shareware version at http://www.explodingart.com/.) Jamming Online With this software users manipulate sliders and dials to influence changes in music in real time. This enables the opportunity for participants to interact with the sound possibilities of a chosen musical style as a focused musical environment. Essentially by moving a slider or dial the user can change the intensity of the musical activity across musical elements such as rhythm, harmony, timbre and volume and the changes they make will respond within the framework of the musical style parameters, updating and recomposing within the timeframe of a quaver/eighth note. This enables the users to play within the style and to hear and influence the shape and structure of the sound. Whilst real time performance using a computer is not new, what is different about this software is that through a network users can create virtual ensembles, which are simultaneously collaborative and interactive. jam2jam was developed using philosophical design principals based on an understanding of ‘meaning’ gained by musicians drawn from both software, live music experiences (Dillon, Student as Maker) and research about how professional composers engage with technology in creative production (Brown, Music Composition). New music technologies have for centuries provided expressive possibilities and an environment where humans can be playful. With jam2jam users can play with complex or simple musical ideas, interact with the musical elements, and hear the changes immediately. When networked they can have these musical experiences collaboratively in a virtual ensemble. Background The initial development of jam2jam began with a survey of the musical tastes of a group of children between the ages of 8-14 in a multi racial community in Delaware, Ohio in the USA as part of the Delaware Children’s Music Festival in 2002. These surveys of ‘the music they liked’ resulted in the researchers purchasing Compact Discs and completing a rule based analysis of the styles. This analysis was then converted into numerical values and algorithms were constructed and used as a structure for the software. The algorithms propose the intensity of range of each style. For example, in the Grunge style the snare drum at low intensity plays a cross stick rim timbre on the second and fourth beat and at high intensity the sound becomes a gated snare sound and plays rhythmic quaver/eighth note triplets. In between these are characteristic rhythmic materials that are less complex than the extreme (triplets). This procedure is replicated across five instruments; drums, percussion, bass, guitar and keyboard. The melodic instruments have algorithms for pitch organisation within the possibilities of the style. These algorithms are the recipes or lesson plans for interactive music making where the student’s gestures control the intensity of the music as it composes in real time. A simple interface was designed (see fig. 1) with a page for each instrument and the mixer. The interface primarily uses dials and sliders for interaction, with radio buttons for timbrel/instrument selection. Once the software was built and installed students were observed using it by videotaping their interaction and interviewing both children and teachers. Observations, which fed into the developmental design, were drawn on a daily basis with the interface and sound engine being regularly updated to accommodate students and teacher requirements. The principals of observation and analysis were based upon a theory of meaningful engagement (Brown, “Modes”, Music Composition; Dillon, “Modelling”, Student as Maker). These adjustments were applied to the software, the curriculum design and to the facilitators’ organisational processes and interactions with the students. The concept of meaningful engagement, which has been applied to this software development process, has provided an effective tool for identifying the location of meaning and describing modes of creative engagement experienced through networked jamming. It also provided a framework for dynamic evaluation and feedback which influences the design with each successive iteration. Defining a Contemporary Musicianship Networked improvisational experiences develop a contemporary musicianship, in which the computer is embraced as an instrument that can be used skillfully in live performance with both acoustic/electric instruments and other network users. The network itself becomes a site for a virtual ensemble where users can experience interaction between ‘players’ in real time. With networked improvisation, cyberspace becomes a venue. Observations have also included performances between two distant locations and ones where computers on the network simultaneously ‘jammed’ with ‘live’ acoustic performers. The Future The future of networked jamming is exciting. There is potential for these environments to replicate complex musical systems and engage participants in musical understandings, linking gesture and sound with concepts of musical knowledge that are constructed within the algorithm and the interface. The dynamic development of Networked Jamming applications involve designs which apply philosophical and pedagogical principles that encourage and sustain meaningful engagement with music making. These are sufficiently complex to allow the revisiting of musical experiences and knowledge at increasingly deeper levels. Conclusion jam2jam is a proof of concept model for networked jamming environments, where people and machines play music in collaborative ensembles. Network jamming requires a contemporary musicianship, which embraces the computer as an instrument, the network as an ensemble and cyberspace as venue for performance. These concepts facilitate access to the ensemble performance of complex musical structures through simple interfaces. It provides the opportunity for users to be creatively immersed in the simultaneous act of listening and performance. jam2jam represents an opportunity for music-makers to have interactive experiences with musical knowledge in a way not otherwise previously available. It enables children, adults and the disabled to enter into a collaborative community where technology mediates a live ensemble performance. The experience could be an ostinato pumping out hip-hop or techno grooves, a Xenakis chaos algorithm, or a minimal ambient soundscape. With the development of new algorithms, a sample engine and creative interface design we believe this concept has amazing possibilities. The real potential of this concept lies in the access that the users have to meaningful engagement with ensemble performance in the production of music, in real time, even with limited previous experience or dexterity.

Jamming culture has become associated with digital manipulation and reuse of materials. As well, the term jamming has long been used by musicians (and other performers) to mean improvisation, especially in collaborative situations. A practice that gets to the heart of both these meanings is live coding; where digital content (music and/or visuals predominantly) is created through computer programming as a performance. During live coding performances digital content is created and presented in real time. Normally the code from the performers screen is displayed via data projection so that the audience can see the unfolding process as well as see or hear the artistic outcome. This article will focus on live coding of music, but the issues it raises for jamming culture apply to other mediums also. Live coding of music uses the computer as an instrument, which is “played” by the direct construction and manipulation of sonic and musical processes. Gestural control involves typing at the computer keyboard but, unlike traditional “keyboard” instruments, these key gestures are usually indirect in their effect on the sonic result because they result in programming language text which is then interpreted by the computer. Some live coding performers, notably Amy Alexander, have played on the duality of the keyboard as direct and indirect input source by using it as both a text entry device, audio trigger, and performance prop. In most cases, keyboard typing produces notational description during live coding performances as an indirect music making, related to what may previously have been called composing or conducting; where sound generation is controlled rather than triggered. The computer system becomes performer and the degree of interpretive autonomy allocated to the computer can vary widely, but is typically limited to probabilistic choices, structural processes and use of pre-established sound generators. In live coding practices, the code is a medium of expression through which creative ideas are articulated. The code acts as a notational representation of computational processes. It not only leads to the sonic outcome but also is available for reflection, reuse and modification. The aspects of music described by the code are open to some variation, especially in relation to choices about music or sonic granularity. This granularity continuum ranges from a focus on sound synthesis at one end of the scale to the structural organisation of musical events or sections at the other end. Regardless of the level of content granularity being controlled, when jamming with code the time constraints of the live performance environment force the performer to develop succinct and parsimonious expressions and to create processes that sustain activity (often using repetition, iteration and evolution) in order to maintain a coherent and developing musical structure during the performance. As a result, live coding requires not only new performance skills but also new ways of describing the structures of and processes that create music. Jamming activities are additionally complex when they are collaborative. Live Coding performances can often be collaborative, either between several musicians and/or between music and visual live coders. Issues that arise in collaborative settings are both creative and technical. When collaborating between performers in the same output medium (e.g., two musicians) the roles of each performer need to be defined. When a pianist and a vocalist improvise the harmonic and melodic roles are relatively obvious, but two laptop performers are more like a guitar duo where each can take any lead, supportive, rhythmic, harmonic, melodic, textual or other function. Prior organisation and sensitivity to the needs of the unfolding performance are required, as they have always been in musical improvisations. At the technical level it may be necessary for computers to be networked so that timing information, at least, is shared. Various network protocols, most commonly Open Sound Control (OSC), are used for this purpose. Another collaboration takes place in live coding, the one between the performer and the computer; especially where the computational processes are generative (as is often the case). This real-time interaction between musician and algorithmic process has been termed Hyperimprovisation by Roger Dean. Jamming cultures that focus on remixing often value the sharing of resources, especially through the movement and treatment of content artefacts such as audio samples and digital images. In live coding circles there is a similarly strong culture of resource sharing, but live coders are mostly concerned with sharing techniques, processes and tools. In recognition of this, it is quite common that when distributing works live coding artists will include descriptions of the processes used to create work and even share the code. This practice is also common in the broader computational arts community, as evident in the sharing of flash code on sites such as Levitated by Jared Tarbell, in the Processing site (Reas & Fry), or in publications such as Flash Maths Creativity (Peters et al.). Also underscoring this culture of sharing, is a prioritising of reputation above (or prior to) profit. As a result of these social factors most live coding tools are freely distributed. Live Coding tools have become more common in the past few years. There are a number of personalised systems that utilise various different programming languages and environments. Some of the more polished programs, that can be used widely, include SuperCollider (McCartney), Chuck (Wang & Cook) and Impromptu (Sorensen). While these environments all use different languages and varying ways of dealing with sound structure granularity, they do share some common aspects that reveal the priorities and requirements of live coding. Firstly, they are dynamic environments where the musical/sonic processes are not interrupted by modifications to the code; changes can be made on the fly and code is modifiable at runtime. Secondly, they are text-based and quite general programming environments, which means that the full leverage of abstract coding structures can be applied during live coding performances. Thirdly, they all prioritise time, both at architectural and syntactic levels. They are designed for real-time performance where events need to occur reliably. The text-based nature of these tools means that using them in live performance is barely distinguishable from any other computer task, such as writing an email, and thus the practice of projecting the environment to reveal the live process has become standard in the live coding community as a way of communicating with an audience (Collins). It is interesting to reflect on how audiences respond to the projection of code as part of live coding performances. In the author’s experience as both an audience member and live coding performer, the reception has varied widely. Most people seem to find it curious and comforting. Even if they cannot follow the code, they understand or are reassured that the performance is being generated by the code. Those who understand the code often report a sense of increased anticipation as they see structures emerge, and sometimes opportunities missed. Some people dislike the projection of the code, and see it as a distasteful display of virtuosity or as a distraction to their listening experience. The live coding practitioners tend to see the projection of code as a way of revealing the underlying generative and gestural nature of their performance. For some, such as Julian Rohrhuber, code projection is a way of revealing ideas and their development during the performance. “The incremental process of livecoding really is what makes it an act of public reasoning” (Rohrhuber). For both audience and performer, live coding is an explicitly risky venture and this element of public risk taking has long been central to the appreciation of the performing arts (not to mention sport and other cultural activities). The place of live coding in the broader cultural setting is still being established. It certainly is a form of jamming, or improvisation, it also involves the generation of digital content and the remixing of cultural ideas and materials. In some ways it is also connected to instrument building. Live coding practices prioritise process and therefore have a link with conceptual visual art and serial music composition movements from the 20th century. Much of the music produced by live coding has aesthetic links, naturally enough, to electronic music genres including musique concrète, electronic dance music, glitch music, noise art and minimalism. A grouping that is not overly coherent besides a shared concern for processes and systems. Live coding is receiving greater popular and academic attention as evident in recent articles in Wired (Andrews), ABC Online (Martin) and media culture blogs including The Teeming Void (Whitelaw 2006). Whatever its future profile in the boarder cultural sector the live coding community continues to grow and flourish amongst enthusiasts. The TOPLAP site is a hub of live coding activities and links prominent practitioners including, Alex McLean, Nick Collins, Adrian Ward, Julian Rohrhuber, Amy Alexander, Frederick Olofsson, Ge Wang, and Andrew Sorensen. These people and many others are exploring live coding as a form of jamming in digital media and as a way of creating new cultural practices and works.

A heterogeneous object (HO) refers to a solid component consisting of two or more material primitives distributed either continuously or discontinuously within the object. HOs are commonly divided into three categories. The first category has distinct material domains separating the different materials. The second, called functionally graded materials (FGMs), has continuous variation of material composition that produces gradient in material properties. The third category allows for any combinations of the first two categories within the same part. Modeling and manufacturing of HOs has recently generated more interest due to the advent of additive manufacturing (AM) technology that makes it possible to build such parts. Directed energy deposition (DED) processes have the potential for depositing multiple powdered materials in various compositions in the process of creating a single layer of material. To make this possible, tool paths that provide proper positioning of the deposition head and proper control over the material composition are required. This paper presents an approach for automatically generating the toolpath for any type of HO considering the material composition changes that are required on each layer. The toolpath generation takes into account the physical limitations of the machine associated with powder delivery and ability to continually grade the materials. Simulation results using the toolpath generation methodology are demonstrated by several example parts.

In 1956, John Cage predicted that “in the future, records will be made from records” (Duffel, 202). Certainly, musical creativity has always involved a certain amount of appropriation and adaptation of previous works. For example, Vivaldi appropriated and adapted the “Cum sancto spiritu” fugue of Ruggieri’s Gloria (Burnett, 4; Forbes, 261). If stuck for a guitar solo on stage, Keith Richards admits that he’ll adapt Buddy Holly for his own purposes (Street, 135). Similarly, Nirvana adapted the opening riff from Killing Jokes’ “Eighties” for their song “Come as You Are”. Musical “quotation” is actively encouraged in jazz, and contemporary hip-hop would not exist if the genre’s pioneers and progenitors had not plundered and adapted existing recorded music. Sampling technologies, however, have taken musical adaptation a step further and realised Cage’s prediction. Hardware and software samplers have developed to the stage where any piece of audio can be appropriated and adapted to suit the creative impulses of the sampling musician (or samplist). The practice of sampling challenges established notions of creativity, with whole albums created with no original musical input as most would understand it—literally “records made from records.” Sample-based music is premised on adapting audio plundered from the cultural environment. This paper explores the ways in which technology is used to adapt previous recordings into new ones, and how musicians themselves have adapted to the potentials of digital technology for exploring alternative approaches to musical creativity. Sampling is frequently defined as “the process of converting an analog signal to a digital format.” While this definition remains true, it does not acknowledge the prevalence of digital media. The “analogue to digital” method of sampling requires a microphone or instrument to be recorded directly into a sampler. Digital media, however, simplifies the process. For example, a samplist can download a video from YouTube and rip the audio track for editing, slicing, and manipulation, all using software within the noiseless digital environment of the computer. Perhaps it is more prudent to describe sampling simply as the process of capturing sound. Regardless of the process, once a sound is loaded into a sampler (hardware or software) it can be replayed using a MIDI keyboard, trigger pad or sequencer. Use of the sampled sound, however, need not be a faithful rendition or clone of the original. At the most basic level of manipulation, the duration and pitch of sounds can be altered. The digital processes that are implemented into the Roland VariOS Phrase Sampler allow samplists to eliminate the pitch or melodic quality of a sampled phrase. The phrase can then be melodically redefined as the samplist sees fit: adapted to a new tempo, key signature, and context or genre. Similarly, software such as Propellerhead’s ReCycle slices drum beats into individual hits for use with a loop sampler such as Reason’s Dr Rex module. Once loaded into Dr Rex, the individual original drum sounds can be used to program a new beat divorced from the syncopation of the original drum beat. Further, the individual slices can be subjected to pitch, envelope (a component that shapes the volume of the sound over time) and filter (a component that emphasises and suppresses certain frequencies) control, thus an existing drum beat can easily be adapted to play a new rhythm at any tempo. For example, this rhythm was created from slicing up and rearranging Clyde Stubblefield’s classic break from James Brown’s “Funky Drummer”. Sonic adaptation of digital information is not necessarily confined to the auditory realm. An audio editor such as Sony’s Sound Forge is able to open any file format as raw audio. For example, a Word document or a Flash file could be opened with the data interpreted as audio. Admittedly, the majority of results obtained are harsh white noise, but there is scope for serendipitous anomalies such as a glitchy beat that can be extracted and further manipulated by audio software. Audiopaint is an additive synthesis application created by Nicolas Fournel for converting digital images into audio. Each pixel position and colour is translated into information designating frequency (pitch), amplitude (volume) and pan position in the stereo image. The user can determine which one of the three RGB channels corresponds to either of the stereo channels. Further, the oscillator for the wave form can be either the default sine wave or an existing audio file such as a drum loop can be used. The oscillator shapes the end result, responding to the dynamics of the sine wave or the audio file. Although Audiopaint labours under the same caveat as with the use of raw audio, the software can produce some interesting results. Both approaches to sound generation present results that challenge distinctions between “musical sound” and “noise”. Sampling is also a cultural practice, a relatively recent form of adaptation extending out of a time honoured creative aesthetic that borrows, quotes and appropriates from existing works to create new ones. Different fields of production, as well as different commentators, variously use terms such as “co-creative media”, “cumulative authorship”, and “derivative works” with regard to creations that to one extent or another utilise existing works in the production of new ones (Coombe; Morris; Woodmansee). The extent of the sampling may range from subtle influence to dominating significance within the new work, but the constant principle remains: an existing work is appropriated and adapted to fit the needs of the secondary creator. Proponents of what may be broadly referred to as the “free culture” movement argue that creativity and innovation inherently relies on the appropriation and adaptation of existing works (for example, see Lessig, Future of Ideas; Lessig, Free Culture; McLeod, Freedom of Expression; Vaidhyanathan). For example, Gwen Stefani’s 2004 release “Rich Girl” is based on Louchie Lou and Michie One’s 1994 single of the same title. Lou and One’s “Rich Girl”, in turn, is a reggae dance hall adaptation of “If I Were a Rich Man” from Fiddler on the Roof. Stefani’s “na na na” vocal riff shares the same melody as the “Ya ha deedle deedle, bubba bubba deedle deedle dum” riff from Fiddler on the Roof. Samantha Mumba adapted David Bowie’s “Ashes to Ashes” for her second single “Body II Body”. Similarly, Richard X adapted Tubeway Army’s “Are ‘Friends’ Electric?’ and Adina Howard’s “Freak Like Me” for a career saving single for Sugababes. Digital technologies enable and even promote the adaptation of existing works (Morris). The ease of appropriating and manipulating digital audio files has given rise to a form of music known variously as mash-up, bootleg, or bastard pop. Mash-ups are the most recent stage in a history of musical appropriation and they epitomise the sampling aesthetic. Typically produced in bedroom computer-based studios, mash-up artists use software such as Acid or Cool Edit Pro to cut up digital music files and reassemble the fragments to create new songs, arbitrarily adding self-composed parts if desired. Comprised almost exclusively from sections of captured music, mash-ups have been referred to as “fictional pop music” because they conjure up scenarios where, for example, Destiny’s Child jams in a Seattle garage with Nirvana or the Spice Girls perform with Nine Inch Nails (Petridis). Once the initial humour of the novelty has passed, the results can be deeply alluring. Mash-ups extract the distinctive characteristics of songs and place them in new, innovative contexts. As Dale Lawrence writes: “the vocals are often taken from largely reviled or ignored sources—cornball acts like Aguilera or Destiny’s Child—and recast in wildly unlikely contexts … where against all odds, they actually work”. Similarly, Crawford argues that “part of the art is to combine the greatest possible aesthetic dissonance with the maximum musical harmony. The pleasure for listeners is in discovering unlikely artistic complementarities and revisiting their musical memories in mutated forms” (36). Sometimes the adaptation works in the favour of the sampled artist: George Clinton claims that because of sampling he is more popular now than in 1976—“the sampling made us big again” (Green). The creative aspect of mash-ups is unlike that usually associated with musical composition and has more in common with DJing. In an effort to further clarify this aspect, we may regard DJ mixes as “mash-ups on the fly.” When Grandmaster Flash recorded his quilt-pop masterpiece, “Adventures of Grandmaster Flash on the Wheels of Steel,” it was recorded while he performed live, demonstrating his precision and skill with turntables. Modern audio editing software facilitates the capture and storage of sound, allowing mash-up artists to manipulate sounds bytes outside of “real-time” and the live performance parameters within which Flash worked. Thus, the creative element is not the traditional arrangement of chords and parts, but rather “audio contexts”. If, as Riley pessimistically suggests, “there are no new chords to be played, there are no new song structures to be developed, there are no new stories to be told, and there are no new themes to explore,” then perhaps it is understandable that artists have searched for new forms of musical creativity. The notes and chords of mash-ups are segments of existing works sequenced together to produce inter-layered contexts rather than purely tonal patterns. The merit of mash-up culture lies in its function of deconstructing the boundaries of genre and providing new musical possibilities. The process of mashing-up genres functions to critique contemporary music culture by “pointing a finger at how stifled and obvious the current musical landscape has become. … Suddenly rap doesn’t have to be set to predictable funk beats, pop/R&B ballads don’t have to come wrapped in cheese, garage melodies don’t have to recycle the Ramones” (Lawrence). According to Theodor Adorno, the Frankfurt School critic, popular music (of his time) was irretrievably simplistic and constructed from easily interchangeable, modular components (McLeod, “Confessions”, 86). A standardised and repetitive approach to musical composition fosters a mode of consumption dubbed by Adorno “quotation listening” and characterised by passive acceptance of, and obsession with, a song’s riffs (44-5). As noted by Em McAvan, Adorno’s analysis elevates the producer over the consumer, portraying a culture industry controlling a passive audience through standardised products (McAvan). The characteristics that Adorno observed in the popular music of his time are classic traits of contemporary popular music. Mash-up artists, however, are not representative of Adorno’s producers for a passive audience, instead opting to wrest creative control from composers and the recording industry and adapt existing songs in pursuit of their own creative impulses. Although mash-up productions may consciously or unconsciously criticise the current state of popular music, they necessarily exist in creative symbiosis with the commercial genres: “if pop songs weren’t simple and formulaic, it would be much harder for mashup bedroom auteurs to do their job” (McLeod, “Confessions”, 86). Arguably, when creating mash-ups, some individuals are expressing their dissatisfaction with the stagnation of the pop industry and are instead working to create music that they as consumers wish to hear. Sample-based music—as an exercise in adaptation—encourages a Foucauldian questioning of the composer’s authority over their musical texts. Recorded music is typically a passive medium in which the consumer receives the music in its original, unaltered form. DJ Dangermouse (Brian Burton) breached this pact to create his Grey Album, which is a mash-up of an a cappella version of Jay-Z’s Black Album and the Beatles’ eponymous album (also known as the White Album). Dangermouse says that “every kick, snare, and chord is taken from the Beatles White Album and is in their original recording somewhere.” In deconstructing the Beatles’ songs, Dangermouse turned the recordings into a palette for creating his own new work, adapting audio fragments to suit his creative impulses. As Joanna Demers writes, “refashioning these sounds and reorganising them into new sonic phrases and sentences, he creates acoustic mosaics that in most instances are still traceable to the Beatles source, yet are unmistakeably distinct from it” (139-40). Dangermouse’s approach is symptomatic of what Schütze refers to as remix culture: an open challenge to a culture predicated on exclusive ownership, authorship, and controlled distribution … . Against ownership it upholds an ethic of creative borrowing and sharing. Against the original it holds out an open process of recombination and creative transformation. It equally calls into question the categories, rifts and borders between high and low cultures, pop and elitist art practices, as well as blurring lines between artistic disciplines. Using just a laptop, an audio editor and a calculator, Gregg Gillis, a.k.a. Girl Talk, created the Night Ripper album using samples from 167 artists (Dombale). Although all the songs on Night Ripper are blatantly sampled-based, Gillis sees his creations as “original things” (Dombale). The adaptation of sampled fragments culled from the Top 40 is part of Gillis’ creative process: “It’s not about who created this source originally, it’s about recontextualising—creating new music. … I’ve always tried to make my own songs” (Dombale). Gillis states that his music has no political message, but is a reflection of his enthusiasm for pop music: “It’s a celebration of everything Top 40, that’s the point” (Dombale). Gillis’ “celebratory” exercises in creativity echo those of various fan-fiction authors who celebrate the characters and worlds that constitute popular culture. Adaptation through sampling is not always centred solely on music. Sydney-based Tom Compagnoni, a.k.a. Wax Audio, adapted a variety of sound bytes from politicians and media personalities including George W. Bush, Alexander Downer, Alan Jones, Ray Hadley, and John Howard in the creation of his Mediacracy E.P.. In one particular instance, Compagnoni used a myriad of samples culled from various media appearances by George W. Bush to recreate the vocals for John Lennon’s Imagine. Created in early 2005, the track, which features speeded-up instrumental samples from a karaoke version of Lennon’s original, is an immediate irony fuelled comment on the invasion of Iraq. The rationale underpinning the song is further emphasised when “Imagine This” reprises into “Let’s Give Peace a Chance” interspersed with short vocal fragments of “Come Together”. Compagnoni justifies his adaptations by presenting appropriated media sound bytes that deliberately set out to demonstrate the way information is manipulated to present any particular point of view. Playing the media like an instrument, Wax Audio juxtaposes found sounds in a way that forces the listener to confront the bias, contradiction and sensationalism inherent in their daily intake of media information. … Oh yeah—and it’s bloody funny hearing George W Bush sing “Imagine”. Notwithstanding the humorous quality of the songs, Mediacracy represents a creative outlet for Compagnoni’s political opinions that is emphasised by the adaptation of Lennon’s song. Through his adaptation, Compagnoni revitalises Lennon’s sentiments about the Vietnam War and superimposes them onto the US policy on Iraq. An interesting aspect of sampled-based music is the re-occurrence of particular samples across various productions, which demonstrates that the same fragment can be adapted for a plethora of musical contexts. For example, Clyde Stubblefield’s “Funky Drummer” break is reputed to be the most sampled break in the world. The break from 1960s soul/funk band the Winstons’ “Amen Brother” (the B-side to their 1969 release “Color Him Father”), however, is another candidate for the title of “most sampled break”. The “Amen break” was revived with the advent of the sampler. Having featured heavily in early hip-hop records such as “Words of Wisdom” by Third Base and “Straight Out of Compton” by NWA, the break “appears quite adaptable to a range of music genres and tastes” (Harrison, 9m 46s). Beginning in the early 1990s, adaptations of this break became a constant of jungle music as sampling technology developed to facilitate more complex operations (Harrison, 5m 52s). The break features on Shy FX’s “Original Nutta”, L Double & Younghead’s “New Style”, Squarepusher’s “Big Acid”, and a cover version of Led Zepplin’s “Whole Lotta Love” by Jane’s Addiction front man Perry Farrell. This is to name but a few tracks that have adapted the break. Wikipedia offers a list of songs employing an adaptation of the “Amen break”. This list, however, falls short of the “hundreds of tracks” argued for by Nate Harrison, who notes that “an entire subculture based on this one drum loop … six seconds from 1969” has developed (8m 45s). The “Amen break” is so ubiquitous that, much like the twelve bar blues structure, it has become a foundational element of an entire genre and has been adapted to satisfy a plethora of creative impulses. The sheer prevalence of the “Amen break” simultaneously illustrates the creative nature of music adaptation as well as the potentials for adaptation stemming from digital technology such as the sampler. The cut-up and rearrangement aspect of creative sampling technology at once suggests the original but also something new and different. Sampling in general, and the phenomenon of the “Amen break” in particular, ensures the longevity of the original sources; sampled-based music exhibits characteristics acquired from the source materials, yet the illegitimate offspring are not their parents. Sampling as a technology for creatively adapting existing forms of audio has encouraged alternative approaches to musical composition. Further, it has given rise to a new breed of musician that has adapted to technologies of adaptation. Mash-up artists and samplists demonstrate that recorded music is not simply a fixed or read-only product but one that can be freed from the composer’s original arrangement to be adapted and reconfigured. Many mash-up artists such as Gregg Gillis are not trained musicians, but their ears are honed from enthusiastic consumption of music. Individuals such as DJ Dangermouse, Gregg Gillis and Tom Compagnoni appropriate, reshape and re-present the surrounding soundscape to suit diverse creative urges, thereby adapting the passive medium of recorded sound into an active production tool.

Our daily environment is surrounded by a paradoxically silent and invisible flow: the coming and going of data through our network cables, routers and wireless devices. This data is not just 1s and 0s, but bits of the conversations, images, sounds, thoughts and other forms of information that result from our interaction with the world around us. If we can speak of a global ambience, it is certainly derived from this constant flow of data. It is an endless murmur that speaks to our machines and gives us a sense of awareness of a certain form of surrounding that is independent from our actual, physical location. The constant “presence” of data around us is something that we have become largely aware of. Already in 1994, Phil Agre stated in an article in WIRED Magazine: “We're so accustomed to data that hardly anyone questions it” (1). Agre indicated that this data is in fact a representation of the world, the discrete bits of information that form the reality we are immersed in. He also proposed that it should be “brought to life” by exploring its relationships with other data and the world itself. A decade later, these relationships had become the core of the new paradigm of the World Wide Web and our interaction with cyberspace. As Mitchell Whitelaw puts it: “The web is increasingly a set of interfaces to datasets ... . On the contemporary web the data pour has become the rule, rather than the exception. The so-called ‘web 2.0’ paradigm further abstracts web content into feeds, real-time flows of XML data” ("Art against Information"). These feeds and flows have been used by artists and researchers in the creation of different forms of dynamic visualisations, in which data is mapped according to a set of parameters in order to summarise it in a single image or structure. Lev Manovich distinguishes in these visualisations those made by artists, to which he refers as “data art”. Unlike other forms of mapping, according to Manovich data art has a precise goal: “The more interesting and at the end maybe more important challenge is how to represent the personal subjective experience of a person living in a data society” (15). Therefore, data artists extract from the bits of information available in cyberspace a dynamic representation of our contemporary environment, the ambience of our digital culture, our shared, intimate and at the same time anonymous, subjectivity. In this article I intend to present some of the ways in which artists have dealt with the murmur of data creatively, exploring the immense amounts of user generated content in forms that interrogate our relationship with the virtual environment and the global community. I will discuss several artistic projects that have shaped the data flow on the Internet in order to take the user back to a state of contemplation, as a listener, an observer, and finally encountering the virtual in a physical form. Listening The concept of ambience particularly evokes an auditory experience related to a given location: in filmmaking, it refers to the sounds of the surrounding space and is the opposite of silence; as a musical genre, ambient music contributes to create a certain atmosphere. In relation to flows of data, it can be said that the applications that analyze Internet traffic and information are “listening” to it, as if someone stands in a public place, overhearing other people's conversations. The act of listening also implies a reception, not an emission, which is a substantial distinction given the fact that data art projects work with given data instead of generating it. As Mitchell Whitelaw states: “Data here is first of all indexical of reality. Yet it is also found, or to put it another way, given. ... Data's creation — in the sense of making a measurement, framing and abstracting something from the flux of the real — is left out” (3). One of the most interesting artistic projects to initially address this sort of “listening” is Carnivore (2001) by the Radical Software Group. Inspired by DCS1000, an e-mail surveillance software developed by the FBI, Carnivore (which was actually the original name of the FBI's program) listens to Internet traffic and serves this data to interfaces (clients) designed by artists, which interpret the provided information in several ways. The data packets can be transformed into an animated graphic, as in amalgamatmosphere (2001) by Joshua Davis, or drive a fleet of radio controlled cars, as in Police State (2003) by Jonah Brucker-Cohen. Yet most of these clients treat data as a more or less abstract value (expressed in numbers) that serves to trigger the reactions in each client. Carnivore clients provide an initial sense of the concept of ambience as reflected in the data circulating the Internet, yet other projects will address this subject more eloquently. Fig. 1: Ben Rubin, Mark Hansen, Listening Post (2001-03). Multimedia installation. Photo: David Allison.Listening Post (2001-04) by Mark Hansen and Ben Rubin is an installation consisting of 231 small electronic screens distributed in a semicircular grid [fig.1: Listening Post]. The screens display texts culled from thousands of Internet chat rooms, which are read by a voice synthesiser and arranged synchronically across the grid. The installation thus becomes a sort of large panel, somewhere between a videowall and an altarpiece, which invites the viewer to engage in a meditative contemplation, seduced by the visual arrangement of the flickering texts scrolling on each screen, appearing and disappearing, whilst sedated by the soft, monotonous voice of the machine and an atmospheric musical soundtrack. The viewer is immersed in a particular ambience generated by the fragmented narratives of the anonymous conversations extracted from the Internet. The setting of the piece, isolated in a dark room, invites contemplation and silence, as the viewer concentrates on seeing and listening. The artists clearly state that their goal in creating this installation was to recreate a sense of ambience that is usually absent in electronic communications: “A participant in a chat room has limited sensory access to the collective 'buzz' of that room or of others nearby – the murmur of human contact that we hear naturally in a park, a plaza or a coffee shop is absent from the online experience. The goal of Listening Post is to collect this buzz and render it at a human scale” (Hansen 114-15). The "buzz", as Hansen and Rubin describe it, is in fact nonexistent in the sense that it does not take place in any physical environment, but is rather the imagined output of the circulation of a myriad blocks of data through the Net. This flow of data is translated into audible and visible signals, thus creating a "murmur" that the viewer can relate to her experience in interacting with other humans. The ambience of a room full of people engaged in conversation is artificially recreated and expanded beyond the boundaries of a real space. By extracting chats from the Internet, the murmur becomes global, reflecting the topics that are being shared by users around the world, in an improvised, ever-changing embodiment of the Zeitgeist, the spirit of the time, or even a certain stream of consciousness on a planetary scale.

L'Attente [The Waiting] (2007) by Gregory Chatonsky is a net art piece that feeds from the data on the Internet to create an open, never-ending fiction in real time [Fig.2: The Waiting]. In this case, the viewer experiences the artwork on her personal computer, as a sort of film in which words, images and sounds are displayed in a continuous sequence, driven by a slow paced soundtrack that confers a sense of unity to the fragmented nature of the work. The data is extracted in real time from several popular sites (photos from Flickr, posts from Twitter, sound effects from Odeo), the connection between image and text being generated by the network itself: the program extracts text from the posts that users write in Twitter, then selects some words to perform a search on the Flickr database and retrieve photos with matching keywords. The viewer is induced to make sense of this concatenation of visual and audible content and thus creates a story by mentally linking all the elements into what Chatonsky defines as "a fiction without narration" (Chatonsky, Flußgeist). The murmur here becomes a story, but without the guiding voice of a narrator. As with Listening Post, the viewer is placed in the role of a witness or a voyeur, subject to an endless flow of information which is not made of the usual contents distributed by mainstream media, but the personal and intimate statements of her peers, along with the images they have collected and the portraits that identify them in the social networks. In contrast to the overdetermination of History suggested by the term Zeitgeist, Chatonsky proposes a different concept, the spirit of the flow or Flußgeist, which derives not from a single idea expressed by multiple voices but from a "voice" that is generated by listening to all the different voices on the Net (Chatonsky, Zeitgeist). Again, the ambience is conceived as the combination of a myriad of fragments, which requires attentive contemplation. The artist describes this form of interacting with the contents of the piece by making a reference to the character of the angel Damiel in Wim Wenders’s film Wings of Desire (Der Himmel über Berlin, 1987): “to listen as an angel distant and proximate the inner voice of people, to place the hand on their insensible shoulder, to hold without being able to hold back” (Chatonsky, Flußgeist). The act of listening as described in Wenders's character illustrates several key aspects of the above mentioned artworks: there is, on the one hand, a receptiveness, carried out by the applications that extract data from the Internet, which cannot be “hold back” by the user, unable to control the flow that is evolving in front of her. On the other hand, the information she receives is always fragmentary, made up of disconnected parts which are, in the words of the artist Lisa Jevbratt, “rubbings ... indexical traces of reality” (1). Observing The observation of our environment takes us to consider the concept of landscape. Landscape, in its turn, acquires a double nature when we compare our relationship with the physical environment and the digital realm. In this sense, Mitchell Whitelaw stresses that while data moves at superhuman speed, the real world seems slow and persistent (Landscape). The overlapping of dynamic, fast-paced, virtual information on a physical reality that seems static in comparison is one of the distinctive traits of the following projects, in which the ambience is influenced by realtime data in a visual form that is particularly subtle, or even invisible to the naked eye. Fig. 3: Carlo Zanni, The Fifth Day (2009). Net artwork. Screenshot retrieved on 4/4/2009. Photo: Carlo Zanni. The Fifth Day (2009) by Carlo Zanni is a net art piece in which the artist has created a narration by displaying a sequence of ten pictures showing a taxi ride in the city of Alexandria [Fig.3: The Fifth Day]. Although still, the images are dynamic in the sense that they are transformed according to data retrieved from the Internet describing the political and cultural status of Egypt, along with data extracted from the user's own identity on the Net, such as her IP or city of residence. Every time a user accesses the website where the artwork is hosted, this data is collected and its values are applied to the photos by cloning or modifying particular elements in them. For instance, a photograph of a street will show as many passersby as the proportion of seats held by women in national parliament, while the reflection in the taxi driver's mirror in another photo will be replaced by a picture taken from Al-Jazeera's website. Zanni addresses the viewer's perception of the Middle East by inserting small bits of additional information and also elements from the viewer's location and culture into the images of the Egyptian city. The sequence is rendered as the trailer of a political thriller, enhanced by a dramatic soundtrack and concluded with the artwork's credits. As with the abovementioned projects, the viewer must adopt a passive role, contemplating the images before her and eventually observing the minute modifications inserted by the data retrieved in real time. Yet, in this case, the ambience is not made manifest by a constant buzz to which one must listen, but quite more subtly it is suggested by the fact that not even a still image is always the same. As if observing a landscape, the overall impression is that nothing has changed while there are minor transformations that denote a constant evolution. Zanni has explored this idea in previous works such as eBayLandscape (2004), in which he creates a landscape image by combining data extracted from several websites, or My Temporary Visiting Position from the Sunset Terrace Bar (2007), in which a view of the city of Ahlen (Germany) is combined with a real time webcam image of the sky in Naples (Italy). Although they may seem self-enclosed, these online, data-driven compositions also reflect the global ambience, the Zeitgeist, in different forms. As Carlo Giordano puts it: "Aesthetically, the work aims to a nearly seamless integration of mixed fragments. The contents of these parts, reflecting political and economical issues ... thematize actuality and centrality, amplifying the author's interest in what everybody is talking about, what happens hic et nunc, what is in the fore of the media and social discourse" (16-17). A landscape made of data, such as Zanni's eBayLandscape, is the most eloquent image of how an invisible layer of information is superimposed over our physical environment. Fig. 4: Clara Boj and Diego Díaz, Red Libre, Red Visible (2004-06). Intervention in the urban space. Photo: Lalalab.Artists Clara Boj and Diego Díaz, moreover, have developed a visualisation of the actual flows of data that permeate the spaces we inhabit. In Red Libre, Red Visible [Free Network, Visible Network] (2004-06), Boj and Díaz used Augmented Reality (AR) technology to display the flows of data in a local wireless network by creating AR marker tags that were placed on the street. A Carnivore client developed by the artists enabled anyone with a webcam pointing towards the marker tag and connected to the Wi-Fi network to see in real time the data packets flowing from their computer towards the tag [Fig.4: Red Libre]. The marker tags therefore served both as a tool for the visualisation of network activity as well as a visual sign of the existence of an open network in a particular urban area. Later on, they added the possibility of inserting custom made messages, 3D shapes and images that would appear when a particular AR marker tag was seen through the lens of the webcam. With this project, Boj and Díaz give the user the ability to observe and interact with a layer of her environment that was previously invisible and in some senses, out of reach. The artists developed this idea further in Observatorio [Observatory] (2008), a sightseeing telescope that reveals the existence of Wi-Fi networks in an urban area. In both projects, an important yet unnoticed aspect of our surroundings is brought into focus. As with Carlo Zanni's projects, we are invited to observe what usually escapes our perception. The ambience in our urban environment has also been explored by Julian Oliver, Clara Boj, Diego Díaz and Damian Stewart in The Artvertiser (2009-10), a hand-held augmented reality (AR) device that allows to substitute advertising billboards with custom made images. As Naomi Klein states in her book No Logo, the public spaces in most cities have been dominated by corporate advertising, allowing little or no space for freedom of expression (Klein 399). Oliver's project faces this situation by enabling a form of virtual culture jamming which converts any billboard-crowded plaza into an unparalleled exhibition space. Using AR technology, the artists have developed a system that enables anyone with a camera phone, smartphone or the customised "artvertiser binoculars" to record and substitute any billboard advertisement with a modified image. The user can therefore interact with her environment, first by observing and being aware of the presence of these commercial spaces and later on by inserting her own creations or those of other artists. By establishing a connection to the Internet, the modified billboard can be posted on sites like Flickr or YouTube, generating a constant feedback between the real location and the Net. Gregory Chatonsky's concept of the Flußgeist, which I mentioned earlier, is also present in these works, visually displaying the data on top of a real environment. Again, the user is placed in a passive situation, as a receptor of the information that is displayed in front of her, but in this case the connection with reality is made more evident. Furthermore, the perception of the environment minimises the awareness of the fragmentary nature of the information generated by the flow of data. Embodying In her introduction to the data visualisation section of her book Digital Art, Christiane Paul stresses the fact that data is “intrinsically virtual” and therefore lacking a particular form of manifestation: “Information itself to a large extent seems to have lost its 'body', becoming an abstract 'quality' that can make a fluid transition between different states of materiality” (Paul 174). Although data has no “body”, we can consider, as Paul suggests, any object containing a particular set of information to be a dataspace in its own. In this sense, a tendency in working with the Internet dataflow is to create a connection between the data and a physical object, either as the end result of a process in which the data has been collected and then transferred to a physical form, or providing a means of physically reshaping the object through the variable input of data. The objectification of data thus establishes a link between the virtual and the real, but in the context of an artwork it also implies a particular meaning, as the following examples will show.Fig. 5: Gregory Chatonsky, Le Registre - The Register (2007). Book shelf and books. Photo: Pau Waelder. In Le Registre [The Register] (2007), Gregory Chatonsky developed a software application that gathers sentences related to feelings found on blogs. These sentences are recorded and put together in the form a 500-page book every hour. Every day, the books are gathered in sets of 24 and incorporated to an infinite library. Chatonsky has created a series of bookshelves to collect the books for one day, therefore turning an abstract process into an object and providing a physical embodiment of the murmur of data that I have described earlier [Fig.5: Le Registre]. As with L'Attente, in this work Chatonsky elaborates on the concept of Flußgeist, by “listening” to a specific set of data (in a similar way as in Hansen and Rubin's Listening Post) and bringing it into salience. The end product of this process is not just a meaningless object but actually what makes this work profoundly ironic: printing the books is a futile effort, but also constitutes a borgesque attempt at creating an endless library of something as ephemeral as feelings. In a similar way, but with different intentions, Jens Wunderling brings the online world to the physical world in Default to Public (2009). A series of objects are located in several public spaces in order to display information extracted from users of the Twitter network. Wunderling's installation projects the tweets on a window or prints them in adhesive labels, while informing the users that their messages have been taken for this purpose. The materialisation of information meant for a virtual environment implies a new approach to the concept of ambiance as described previously, and in this case also questions the intimacy of those participating in social networks. As the artist puts it: "In times of rapid change concerning communication behavior, media access and competence, the project Default to Public aims to raise awareness of the possible effects on our lives and our privacy" (Wunderling 155). Fig. 6: Moisés Mañas, Stock (2009). Networked installation. Photo: Moisés Mañas. Finally, in Stock (2009), Moisés Mañas embodies the flow of data from stock markets in an installation consisting of several trench coats hanging from automated coat hangers which oscillate when the stock values of a certain company rise. The resulting movement of the respective trench coat simulates a person laughing. In this work, Mañas translates the abstract flow of data into a clearly understandable gesture, providing at the same time a comment on the dynamics of stock markets [Fig.6: Stock]. Mañas´s project does not therefore simply create a physical output of a specific information (such as the stock value of a company at any given moment), but instead creates a dynamic sculpture which suggests a different perception of an otherwise abstract data. On the one hand, the trenchcoats have a ghostly presence and, as they move with unnatural spams, they remind us of the Freudian concept of the Uncanny (Das Umheimliche) so frequently associated with robots and artificial intelligence. On the other hand, the image of a person laughing, in the context of stock markets and the current economical crisis, becomes an ironic symbol of the morality of some stockbrokers. In these projects, the ambience is brought into attention by generating a physical output of a particular set of data that is extracted from certain channels and piped into a system that creates an embodiment of this immaterial flow. Yet, as the example of Mañas's project clearly shows, objects have particular meanings that are incorporated into the artwork's concept and remind us that the visualisation of information in data art is always discretionary, shaped in a particular form in order to convey the artist's intentions. Beyond the Buzz The artworks presented in this article revealt that, beyond the murmur of sentences culled from chats and blogs, the flow of data on the Internet can be used to express our difficult relationship with the vast amount of information that surrounds us. As Mitchell Whitelaw puts it: “Data art reflects a contemporary worldview informed by data excess; ungraspable quantity, wide distribution, mobility, heterogeneity, flux. Orienting ourselves in this domain is a constant challenge; the network exceeds any overview or synopsis” (Information). This excess is compared by Lev Manovich with the Romantic concept of the Sublime, that which goes beyond the limits of human measure and perception, and suggests an interpretation of data art as the Anti-Sublime (Manovich 11). Yet, in the projects that I have presented, rather than making sense of the constant flow of data there is a sort of dialogue, a framing of the information under a particular interpretation. Data is channeled through the artworks's interfaces but remains as a raw material, unprocessed to some extent, retrieved from its original context. These works explore the possibility of presenting us with constantly renewed content that will develop and, if the artwork is preserved, reflect the thoughts and visions of the next generations. A work constantly evolving in the present continuous, yet also depending on the uncertain future of social network companies and the ever-changing nature of the Internet. The flow of data will nevertheless remain unstoppable, our ambience defined by the countless interactions that take place every day between our divided self and the growing number of machines that share information with us.

In rejoinder to a New York Times’s article claiming, “the value of used pianos, especially uprights, has plummeted … Instead of selling them … , donating them … or just passing them along … , owners are far more likely to discard them” (Walkin), artists Kathleen Irwin (scenography) and Jeff Morton (sound/composition) responded to this ignoble passing with an installation playing with the borders delineating music, theatre, digital technology, and economies of value using two upright red pianos, sound and video projection—and the sensibility of relational aesthetics. The installation was a collaboration between two artists who share a common interest in the performative qualities of public space and how technological augmentation is used in identificatory and embodied art processes as a means of extending the human body and enhancing the material space of person-to-person interaction. The title of the installation, PLAY, referenced the etymology of the word itself and how it has been variously understood over time, across artistic disciplines, and in digital and physical environments. Fundamentally, it explored the relative value of a material object (the piano) and how its social and cultural signification persists, shifts, is diminished or augmented by technology. The installation was mounted at the Dunlop Art Gallery, in the Regina Public Library (Saskatchewan, Canada, 14 June - 25 August 2013) and, as such, it illustrated the Library’s mandate to support all forms of literacy through community accessibility and forms of public outreach, social arrangements, and encounters. Indirectly, (as this was not the initial focus), it also exemplified the artists’s gentle probing of the ways, means, claims, and values when layering information and enhancing our visual experience as we interact with (literally, walk through) our physical landscapes and environments—“to see the world for what it is,” as Matt Turbow says “and to see the elements within” (Chapeau). The installation reflected on, among other things, the piano as a still potent cultural signifier, the persistent ability of our imagination to make meaning and codify experience even without digital overlay, and the library as an archive and disseminator of public knowledge. The artists questioned whether old technologies such as the piano will lose their hold on us entirely as technological augmentation develops the means to enhance or colonize the natural world, through graphics, sounds, haptic feedback, smell and, eventually, commodified experiences. This paper intends to reflect on our work and initiate a friendly (playful) interdisciplinary discussion about material objects in the age of physical and digital interactivity, and the terms of augmentation as we chose to understand it through our installation. In response to the call proposed by this journal on the subject of augmentation, we considered: 1. How audio/visual apparatuses in the gallery space augmented the piano’s expressivity; 2. How the piano augmented the social function of its physical situation; 3. How the technology augmented random and fragmentary musical phrases, creating a prolonged musical composition; 4. How each spectator augmented the art through his/her subjective engagement: how there is always meaning generated in excess of the artists’s intention. Image 1: Piano installed outside Dunlop Gallery/ Regina Public Library (photo credit: Jeff Morton) To begin, a brief description of the site of the installation is in order. The first of the red pianos was installed outside the main doors of the Central Library, located in the city’s downtown. The library’s entrance is framed within a two-story glass atrium and the red piano repeated the architecture’s function to open the space by breaking down perceived barriers, and beckoning the passersby inside. Reflecting Irwin’s community-oriented, site-specific practice, this was the relational catalyst of the work—the piano made available for anyone to play and enjoy, day or night, an invitation to respond to an object inserted into the shared space of the sidewalk: to explore, as Nicolas Bourriaud suggests, “the art as a state of encounter” (16). It was the centerpiece of the exhibition's outreach, which included the exhibition’s vernissage featuring new music and performance artists in concert, a costume and prop workshop for a late night public choir procession, and a series of artist talks. This was, arguably, a defining characteristic of the work, underscoring how the work of art, in this case the piano itself, its abjection illustrated by the perfunctory means typically used to dispose of them, is augmented or gains value through its social construction, over-and-above any that is originally ascribed to it. As Bourriaud writes, any kind of production takes on a social form which no longer has anything to do with its original usefulness. It acquires exchange value that partly covers and shrouds its primary “nature”. The fact is that a work of art has no a priori useful function—not that it is socially useless, but because it is available and flexible, and has an “infinite tendency”. (42) In the Dunlop’s press release, curator Blair Fornwald also confers a supplemental value ascribed to the reframed material object. She describes how the public space in front of the library, as a place of social interaction and cultural identification—of “being seen”—is augmented by the red piano: its presence in an unfamiliar setting underscores the multitude of creative and performative possibilities inherent within it, possibilities that may extend far beyond playing a simple melody. By extension, its presence asserts that the every day is a social, cultural, and physical environment rich with potentiality and promise. (Fornwald) Juxtaposed with the first red piano, the second was dramatically staged within the Dunlop gallery. The room, painted black, formally replicated the framing and focusing conventions of the theatre: its intention to propose other ways of “being seen” and to suggest the blurring of lines between “on stage and off,” and by extension, “on line and off.” A camera embedded in the front of the piano and a large projection screen in the space provided a celebrity moment for anyone approaching the instrument and implied, arguably, the ubiquitous surveillance associated with public space. Indeed, a plausible way of reading the red piano in the darkened gallery was as a provocation to think about how the digital and physical are increasingly enmeshed in our daily lives (Jurgenson). Lit by a chandelier and staged on a circular red carpet, this piano was also available to be played. Unlike the one outside of the building, it was augmented by speakers, a microphone, and a webcam. Through a custom-built digital system (using MaxMSP software), it recorded and played back the sound and image of everyone who sat down to perform, then repeated and superimposed these over similar previously captured material. Enhanced by the unusual stark acoustics of the gallery, the sound filled the reverberant space. Affixed to the gallery’s back wall was the projection screen made up of sheet music (Bach, Debussy and Mozart) taken from the Irwin family’s piano bench, a veritable time capsule from the 1950s. Image 2: Piano installed inside Dunlop Gallery (photo credit: Jeff Morton) In addition to the centrally placed piano, a miniature red piano was situated near the gallery entrance. It and a single red chair placed near the screen, repeated the vivid colour and drew the eye into and around the space underscoring its theatrical quality. The toy piano functioned as a lighthearted invitation, as well as a serious citation of other artists—Eikoh Sudoh, Margaret Leng Tan, John Cage, and Charles M. Schulz’s “Schroeder”—who have employed the miniature instrument to great advantage. It was intended as an illustration of the infinite resonances that material objects may provide and the diverse ways they may signify contingent on the viewer. Considered in a historical context, in the golden age of the upright and at the turn of the twentieth-century, piano lessons signified for many, the formation of a modern citizen schooled in European culture and values. Owning one of these intricately engineered and often beautiful machines, as one in five households did, reflected the social aspirations of its owners and marked their upward economic mobility (Canadian Encyclopedia). One hundred years later, pianos are often relegated to the basement or dump. Irretrievably out of tune, their currency as musical instruments largely devalued. Nonetheless, their cultural and social value persists, no longer the pervasive marker of status, but through the ways they are mediated by artists who prepare, deconstruct, and leave them to deteriorate in beautiful ways. They seem to retain their hold on us through the natural impulse to engage them kinetically, ergonomically, and metaphorically. Built to be an extension of the human hand, body, and imagination, they are a sublime human-scale augmentation of a precise musical system of notation, and a mechanism evolved over centuries through physical augmentations meant to increase the expressivity of both instrument and player. In PLAY, the use of the pianos referenced both their traditional role in public life, and our current relationship with forms of digital media that have replaced these instruments as our primary means of being linked, informed, and entertained—an affirmation of the positive attributes of technology and a reminder of what we may have lost. Indeed, while this was not necessarily clear from the written responses in the Gallery’s guest book (Gorgeous!: Neat!; Too, too cool!; etc.), we surmised that memory might have played a key role in the experience of the installation, set in motion by the precise arrangement of the few material objects – red piano, the piano bench, red chair, and toy piano, each object designed to fit the shape of the body and hold the memory of physical contact. These were designed to trigger a chain of recollections, each chasing the next; each actively participating in what follows. In the Gallery’s annual exhibition catalogue, Ellen Moffat suggests that the relationship the piano builds with the player is important: “the piano plays and is played by the performer. Performing the piano assigns a posture for the performer in relation to the keyboard physically and figuratively” (Moffat 80). Technically, the piano is the sum of many parts, understandable finally as a discrete mechanical system, but unbounded in imagination and limited only by our capacity to play it. Functionally, it acts as an affective repository of memory and feeling, a tool to control the variables of physical and expressive interaction. In PLAY, the digital system in the gallery piano captured, delayed and displayed audio and video clips according to a rubric of cause and effect. Controlled by computer software designed by Morton, the installation captured musical phrases played randomly by individuals and augmented these notes by playing them back at variable speeds and superimposing one over another—musical phrases iterated and reiterated. The effect was fugue-like—an indeterminate composition with a determinant structure, achieved by intertwining physical and digital systems with musical content supplied by participants. The camera hidden in the front of the piano recorded individuals as they sat at the instrument and, immediately, they saw themselves projected in extreme close up onto the screen behind. As the individual struck a note, their image faded and the screen was filled again with the image of a previous participant abstracted and in slow motion. The effect, we suggest, was dreamlike—an echo or a fleeting fragment of something barely remembered. Like the infinite variations the piano permits, the software was also capable of expressing immense variety—each sound and image adding to an expanding archive in an ever-changing improvised composition developed through iterative call and response. Drawing on elements of relational aesthetics, scenographic representation, and digital technology, in PLAY we attempted to cross disciplines in ways that distinguished it from the other piano projects seen over the past several years. Indeed, the image of the upright piano has resonated in the zeitgeist of the international art scene with colourful uprights placed in public places in urban centers across Europe and North America. Wherever they are, individuals engage enthusiastically with them and they, in turn, become the centre of attention: this is part of their appeal. The pianos seem to evoke a utopian sense of community, however temporary, providing opportunities to rediscover old neighbours and make new friends. In PLAY, we posed two different social and aesthetic encounters—one analogue, real, “off-line” and one digital, theatrical, and “on-line,” illustrating less a false binary between two possible realities that ascribes more value to one than the other, than a world where the digital and the physical comingle. Working within a public library, this was a germane train of thought considering how these institutes struggle to stay relevant in the age of Google search and the promise of technological augmentation. The piano also represents a dichotomy: both a failure to represent and an excess of meaning. For decades replete with social signification, they have now become an encumbrance, fit only for the bone yard. As these monumental relics come to the end of their mechanical life, there is more money made in their disposal than in musical production, and more value in their recycled metals, solid wooden bodies, and ivory keys then in their tone and function. The industry that supported their commodification collapsed years ago, as has the market for their sale and the popular music publishing industry that accompanied it. Of course, pianos will be with us for a long time in one form or another, but their history, as a culturally potent object, has diverged. The assumption could easily follow that they have been rendered useless as an aesthetic, generative, and social object. What this installation offered was the possibility of an alternative ending to the story of this erstwhile entertainment console even as we seek our amusement by other means and through other devices. Not surprisingly, the title of the installation suggests that the consideration of “play,” as social and recuperative engagement, is significant. In his seminal work, Homo Ludens, Johan Huizinga discusses the importance of play, suggesting that it is primary to and a necessary condition of the making of culture. He writes, “In play there is something in play, which transcends the immediate needs of life and imparts meaning to the action” (Huizinga 97). According to games theorist Mary Flanagan, playing may serve as a way of creating something beautiful, offering frameworks for new ways of thinking, exploring divergent logic, or for imaging what is possible. She writes, “Games, both digital and analog, offer a space to explore creativity, agency, representation and emergent behaviour” (Flanagan 2010). In reaching out to Regina’s downtown community, the Dunlop Art Gallery dispersed some of the playfulness of PLAY in planned and accidental ways, as the outdoor piano became a daily destination for individuals who live rough or in the city’s hostels, some of whom who have enviable musical skills and considerable stage presence. One man came daily with sheet music in hand to practice on the indoor piano—ignoring the inevitable echo and repeat that the software triggered. Another young woman appeared regularly to perform at the outdoor piano, her umbrella raised against sun and rain, wedged under her arm to keep both hands free. Children invariably drew parents to it as they entered or exited the library—for some it may have been the first time they had touched such an instrument. Overall, in press, blogs, and the visitors’s book, responses to the pianos were enthusiastic and positive. One blogger wrote in response to an online publication, Art, Music, News (Beatty), chapeau June 13, 2013 at 11:51am this is most definitely up and running, and it would be interesting to see/hear all that will go on with that red piano. my two-and-a-half year old daughter and i jammed a bit yesterday morning, while a stranger watched and listened, then insisted that i play the same mostly crappy c-blues again while he sang! so i did, and he did, and my daughter and i learned a bit about what he feels about his dog via his singing. it was the highlight of the day for us—I mean really, jamming outside on a very red upright piano with strangers—good times! (Simpson) As evidence of public approbation, for the better part of the summer it stood unprotected on the sidewalk in front of the library encountering only one minor incident of defacement—a rather fragile tag in white spray paint, someone’s name in proper cursive writing. Once repaired and retuned, it became a dynamic focus for the annual Folk Festival that takes over the area for a week in August. In these ways, PLAY fulfilled the Library’s aim of encouraging literacy and reinforcing a sense of community—a social augmentation, in a manner of speaking. As Moffat writes, it encourages the social dimension of participation through community-engagement and dialogic practices. It blurs distinctions between spectator and participant, professional and amateur. It generates relationships between people or social actions. (Moffat 76) Finally, PLAY toyed with the overtones of the word itself—as verb, noun, and adjective—signifier, and metaphor. The title illustrated its obvious current potential and evoked the piano’s past, referencing the glittering world of the stage. While many may have more memories of seeing pianos in disrepair than in the concert hall, its iconic stage setting is never far from the imagination, although this too changes as people from other cultures and backgrounds recognize little cultural capital in such activity. In current vernacular, the word “play” also implies the re-imagination of ourselves in the digital overlays of the future. So we ask, what will be the fate of the piano and its meme in the 22nd century? Will the augmentation of reality enhance our experience of the world in inverse proportion to a loss of social interaction? Conclusion In her essay, Moffat notes that as digital technology replaces the analog piano, a surplus of second-hand uprights has become available. Citing artists Luke Jerram, Monica Yunus, and Camille Zamora (among others), she argues that the use of them as public art coincides with their disappearance, suggesting a farewell or memorial to a collective cultural icon (Moffat 76). What is there in this piece of furniture that speaks to us in art practice? The answer, it would seem, is potential. In a curatorial interview, Irwin suggested the possibility that beyond the artist’s initial meaning, there is always something more—an augmentation. The pleasure of discovering this supplement is part of the pleasure of the subjective experience of the spectator. Similarly, the aleatoric in music composition, refers to the pursuit of chance as a formal determinant and its openness to individual interpretation at the moment of reception. For Morton, the randomness of memory and affect are key components in composition. They cannot be predicted, controlled or quantified; nor can they be denied. There is no correct interpretation or response to music or, indeed, to relational art practice. Moffat concludes, as a multi-faceted media installation, PLAY proposed “a suite, chorus or a polyphony of things” (Moffat 76). Depending on your point of reference, the installation provided a dynamic venue for considering our relationships with material objects, with each other and with new technologies asking how they may or may not augment our reality in ways that supplement real-time, person-to-person interaction.

This article reflects on part of a three-year battle over the redevelopment of an iconic Melbourne music venue, the Palace-Metro Nightclub (the Palace), involving the tactical use of Facebook Page data at trial. We were invited by the Save the Palace group, Melbourne City Council and the National Trust of Australia to provide Facebook Page data analysis as evidence of the social value of the venue at an appeals trial heard at the Victorian Civil Administration Tribunal (VCAT) in 2016. We take a reflexive ethnographic approach here to explore the data production, collection and analysis processes as these represent and constitute a “data public”.Although the developers won the appeal and were able to re-develop the site, the court accepted the validity of social media data as evidence of the building’s social value (Jinshan Investment Group Pty Ltd v Melbourne CC [2016] VCAT 626, 117; see also Victorian Planning Reports). Through the case, we elaborate on the concept of data publics by considering the “affordising” (Pollock) processes at play when extracting, analysing and visualising social media data. Affordising refers to the designed, deliberate and incidental effects of datafication and highlights the need to attend to the capacities for data collection and processing as they produce particular analytical outcomes. These processes foreground the compositional character of data publics, and the unevenness of data literacies (McCosker “Data Literacies”; Gray et al.) as a factor of the interpersonal and institutional capacity to read and mobilise data for social outcomes.We begin by reconsidering the often-assumed connection between social media data and their publics. Taking onboard theoretical accounts of publics as problem-oriented (Dewey) and dynamically constituted (Kelty), we conceptualise data publics through the key elements of a) consequentiality, b) sufficient connection over time, c) affective or emotional qualities of connection and interaction with the events. We note that while social data analytics may be a powerful tool for public protest, it equally affords use against public interests and introduces risks in relation to a lack of transparency, access or adequate data literacy.Urban Protest and Data Publics There are many examples globally of the use of social media to engage publics in battles over urban development or similar issues (e.g. Fredericks and Foth). Some have asked how social media might be better used by neighborhood organisations to mobilise protest and save historic buildings, cultural landmarks or urban sites (Johnson and Halegoua). And we can only note here the wealth of research literature on social movements, protest and social media. To emphasise Gerbaudo’s point, drawing on Mattoni, we “need to account for how exactly the use of these media reshapes the ‘repertoire of communication’ of contemporary movements and affects the experience of participants” (2). For us, this also means better understanding the role that social data plays in both aiding and reshaping urban protest or arming third sector groups with evidence useful in social institutions such as the courts.New modes of digital engagement enable forms of distributed digital citizenship, which Meikle sees as the creative political relationships that form through exercising rights and responsibilities. Associated with these practices is the transition from sanctioned, simple discursive forms of social protest in petitions, to new indicators of social engagement in more nuanced social media data and the more interactive forms of online petition platforms like change.org or GetUp (Halpin et al.). These technical forms code publics in specific ways that have implications for contemporary protest action. That is, they provide the operational systems and instructions that shape social actions and relationships for protest purposes (McCosker and Milne).All protest and social movements are underwritten by explicit or implicit concepts of participatory publics as these are shaped, enhanced, or threatened by communication technologies. But participatory protest publics are uneven, and as Kelty asks: “What about all the people who are neither protesters nor Twitter users? In the broadest possible sense this ‘General Public’ cannot be said to exist as an actual entity, but only as a kind of virtual entity” (27). Kelty is pointing to the porous boundary between a general public and an organised public, or formal enterprise, as a reminder that we cannot take for granted representations of a public, or the public as a given, in relation to Like or follower data for instance.If carefully gauged, the concept of data publics can be useful. To start with, the notions of publics and publicness are notoriously slippery. Baym and boyd explore the differences between these two terms, and the way social media reconfigures what “public” is. Does a Comment or a Like on a Facebook Page connect an individual sufficiently to an issues-public? As far back as the 1930s, John Dewey was seeking a pragmatic approach to similar questions regarding human association and the pluralistic space of “the public”. For Dewey, “the machine age has so enormously expanded, multiplied, intensified and complicated the scope of the indirect consequences [of human association] that the resultant public cannot identify itself” (157). To what extent, then, can we use data to constitute a public in relation to social protest in the age of data analytics?There are numerous well formulated approaches to studying publics in relation to social media and social networks. Social network analysis (SNA) determines publics, or communities, through links, ties and clustering, by measuring and mapping those connections and to an extent assuming that they constitute some form of sociality. Networked publics (Ito, 6) are understood as an outcome of social media platforms and practices in the use of new digital media authoring and distribution tools or platforms and the particular actions, relationships or modes of communication they afford, to use James Gibson’s sense of that term. “Publics can be reactors, (re)makers and (re)distributors, engaging in shared culture and knowledge through discourse and social exchange as well as through acts of media reception” (Ito 6). Hashtags, for example, facilitate connectivity and visibility and aid in the formation and “coordination of ad hoc issue publics” (Bruns and Burgess 3). Gray et al., following Ruppert, argue that “data publics are constituted by dynamic, heterogeneous arrangements of actors mobilised around data infrastructures, sometimes figuring as part of them, sometimes emerging as their effect”. The individuals of data publics are neither subjugated by the logics and metrics of digital platforms and data structures, nor simply sovereign agents empowered by the expressive potential of aggregated data (Gray et al.).Data publics are more than just aggregates of individual data points or connections. They are inherently unstable, dynamic (despite static analysis and visualisations), or vibrant, and ephemeral. We emphasise three key elements of active data publics. First, to be more than an aggregate of individual items, a data public needs to be consequential (in Dewey’s sense of issues or problem-oriented). Second, sufficient connection is visible over time. Third, affective or emotional activity is apparent in relation to events that lend coherence to the public and its prevailing sentiment. To these, we add critical attention to the affordising processes – or the deliberate and incidental effects of datafication and analysis, in the capacities for data collection and processing in order to produce particular analytical outcomes, and the data literacies these require. We return to the latter after elaborating on the Save the Palace case.Visualising Publics: Highlighting Engagement and IntensityThe Palace theatre was built in 1912 and served as a venue for theatre, cinema, live performance, musical acts and as a nightclub. In 2014 the Heritage Council decided not to include the Palace on Victoria’s heritage register and hence opened the door for developers, but Melbourne City Council and the National Trust of Australia opposed the redevelopment on the grounds of the building’s social significance as a music venue. Similarly, the Save the Palace group saw the proposed redevelopment as affecting the capacity of Melbourne CBD to host medium size live performances, and therefore impacting deeply on the social fabric of the local music scene. The Save the Palace group, chaired by Rebecca Leslie and Michael Raymond, maintained a 36,000+ strong Facebook Page and mobilised local members through regular public street protests, and participated in court proceedings in 2015 and February 2016 with Melbourne City Council and National Trust Australia. Joining the protesters in the lead up to the 2016 appeals trial, we aimed to use social media engagement data to measure, analyse and present evidence of the extent and intensity of a sustained protest public. The evidence we submitted had to satisfy VCAT’s need to establish the social value of the building and the significance of its redevelopment, and to explain: a) how social media works; b) the meaning of the number of Facebook Likes on the Save The Palace Page and the timing of those Likes, highlighting how the reach and Likes pick up at significant events; and c) whether or not a representative sample of Comments are supportive of the group and the Palace Theatre (McCosker “Statement”). As noted in the case (Jinshan, 117), where courts have traditionally relied on one simple measure for contemporary social value – the petition – our aim was to make use of the richer measures available through social media data, to better represent sustained engagement with the issues over time.Visualising a protest public in this way raises two significant problems for a workable concept of data publics. The first involves the “affordising” (Pollock) work of both the platform and our data analysis. This concerns the role played by data access and platform affordances for data capture, along with methodological choices made to best realise or draw out the affordances of the data for our purposes. The second concerns the issue of digital and data literacies in both the social acts that help to constitute a data public in the first place, and the capacity to read and write public data to represent those activities meaningfully. That is, Facebook and our analysis constitutes a data public in certain ways that includes potentially opaque decisions or processes. And citizens (protesters or casual Facebook commenters alike) along with social institutions (like the courts) have certain uneven capacity to effectively produce or read public protest-oriented data. The risk here, which we return to in the final section, lies in the potential for misrepresentation of publics through data, exclusions of access and ownership of data, and the uneven digital literacies at each stage of data production, analysis and sensemaking.Facebook captures data about individuals in intricate detail. Its data capture strategies are geared toward targeting for the purposes of marketing, although only a small subset of the data is publicly available through the Facebook Application Programming Interface (API), which is a kind of data “gateway”. The visible page data tells only part of the story. The total Page Likes in February 2016 was 36,828, representing a sizeable number of followers, mainly located in Melbourne but including 45 countries in total and 38 different languages. We extracted a data set of 268,211 engagements with the Page between February 2013 and August 2015. This included 45,393 post Likes and 9,139 Comments. Our strategy was to demarcate a structurally defined “community” (in the SNA sense of that term as delineating clusters of people, activities and links within a broader network), by visualising the interactions of Facebook users with Posts over time, and then examine elements of intensity of engagement. In other words, we “affordised” the network data using SNA techniques to most clearly convey the social value of the networked public.We used a combination of API access and Facebook’s native Insights data and analytics to extract use-data from that Page between June 2013 and December 2015. Analysis of a two-mode or bipartite network consisting of users and Posts was compiled using vosonSML, a package in the R programming language created at Australian National University (Graham and Ackland) and visualised with Gephi software. In this network, the nodes (or vertices) represent Facebook users and Facebook Posts submitted on the Page, and ties (or edges) between nodes represent whether a user has commented on and/or liked a post. For example, a user U might have liked Post A and commented on Post B. Additionally, a weight value is assigned for the Comments ties, indicating how many times a user commented on a particular post (note that users can only like Posts once). We took these actions as demonstrating sufficient connection over time in relation to an issue of common concern.Figure 1: Network visualisation of activity on the Save the Palace Facebook Page, June 2013 to December 2015. The colour of the nodes denotes which ‘community’ cluster they belong to (computed via the Infomap algorithm) and nodes are sized by out-degree (number of Likes/Comments made by users to Posts). The graph layout is computed via the Force Atlas 2 algorithm.Community detection was performed on the network using the Infomap algorithm (Rosvall and Bergstrom), which is suited to large-scale weighted and directed networks (Henman et al.). This analysis reveals two large and two smaller clusters or groups represented by colour differences (Fig. 1). Broadly, this suggests the presence of several clusters amongst a sustained network engaging with the page over the three years. Beyond this, a range of other colours denoting smaller clusters indicates a diversity of activity and actors co-participating in the network as part of a broader community.The positioning of nodes within the network is not random – the visualisation is generated by the Force Atlas 2 algorithm (Jacomy et al.) that spatially sorts the nodes through processes of attraction and repulsion according to the observed patterns of connectivity. As we would expect, the two-dimensional spatial arrangement of nodes conforms to the community clustering, helping us to visualise the network in the form of a networked public, and build a narrative interpretation of “what is going on” in this online social space.Social value for VCAT was loosely defined as a sense of connection, sentiment and attachment to the venue. While we could illustrate the extent of the active connections of those engaging with the Page, the network map does not in itself reveal much about the sentiment, or the emotional attachment to the Save the Palace cause. This kind of affect can be understood as “the energy that drives, neutralizes, or entraps networked publics” (Papacharissi 7), and its measure presents a particular challenge, but also interest, for understanding a data public. It is often measured through sentiment analysis of content, but we targeted reach and engagement events – particular moments that indicated intense interaction with the Page and associated events.Figure 2: Save the Palace Facebook Page: Organic post reach November—December 2014The affective connection and orientation could be demonstrated through two dimensions of post “reach”: average reach across the lifespan of the Page, and specific “reach-events”. Average reach illustrates the sustained engagement with the Page over time. Average un-paid reach for Posts with links (primarily news and legal updates), was 12,015 or 33% of the total follower base – a figure well above the standard for Community Page reach at that time. Reach-events indicated particular points of intensity and illustrates the Page’s ability to resonate publicly. Figure 2 points to one such event in November 2015, when news circulated that the developers were defying stop-work orders and demolishing parts of The Palace. The 100k reach indicated intense and widespread activity – Likes, Shares, Comments – in a short timeframe. We examined Comment activity in relation to specific reach events to qualify this reach event and illustrate the sense of outrage directed toward the developers, and expressions of solidarity toward those attempting to stop the redevelopment. Affordising Data Publics and the Transformative Work of AnalyticsEach stage of deriving evidence of social value through Page data, from building public visibility and online activity to analysis and presentation at VCAT, was affected by the affordising work of the protesters involved (particularly the Page Admins), civil society groups, platform features and data structures and our choices in analysis and presentation. The notion of affordising is useful here because, as Pollock defines the term, it draws attention to the transformative work of metrics, analytics, platform features and other devices that re-package social activity through modes of datafication and analysis. The Save the Palace group mobilised in a particular way so as to channel their activities, make them visible and archival, to capture the resonant effects of their public protest through a platform that would best make that public visible to itself. The growth of the interest in the Facebook Page feeds back on itself reflexively as more people encounter it and participate. Contrary to critiques of “clicktivism”, these acts combine digital-material events and activities that were to become consequential for the public protest – such as the engagement activities around the November 2015 event described in Figure 2.In addition, presenting the research in court introduced particular hurdles, in finding “the meaningful data” appropriate to the needs of the case, “visualizing social data for social purposes”, and the need to be “evocative as well as accurate” (Donath, 16). The visualisation and presentation of the data needed to afford a valid and meaningful expression of the social significance the Palace. Which layout algorithm to use? What scale do we want to use? Which community detection algorithm and colour scheme for nodes? These choices involve challenges regarding legibility of visualisations of public data (McCosker and Wilken; Kennedy et al.).The transformative actions at play in these tactics of public data analysis can inform other instances of data-driven protest or social participation, but also leave room for misuse. The interests of developers, for example, could equally be served by monitoring protesters’ actions through the same data, or by targeting disagreement or ambiguity in the data. Similarly, moves by Facebook to restrict access to Page data will disproportionately affect those without the means to pay for access. These tactics call for further work in ethical principles of open data, standardisation and data literacies for the courts and those who would benefit from use of their own public data in this way.ConclusionsWe have argued through the case of the Save the Palace protest that in order to make use of public social media data to define a data public, multiple levels of data literacy, access and affordising are required. Rather than assuming that public data simply constitutes a data public, we have emphasised: a) the consequentiality of the movement; b) sufficient connection over time; and c) affective or emotional qualities of connection and interaction with public events. This includes the activities of the core members of the Save the Palace protest group, and the tens of thousands who engaged in some way with the Page. It also involves Facebook’s data affordances as these allow for the extraction of public data, alongside our choices in analysis and visualisation, and the court’s capacity and openness to accept all of this as indicative of the social value (connections, sentiment, attachment) it sought for the case. The Senior Member and Member presiding over the case had little knowledge of Facebook or other social media platforms, did not use them, and hence themselves had limited capacity to recognise the social and cultural nuances of activities that took place through the Facebook Page. This does not exclude the use of the data but made it more difficult to present a picture of the relevance and consequence of the data for understanding the social value evident in the contested building. While the court’s acceptance of the analysis as evidence is a significant starting point, further work is required to ensure openness, standardisation and ethical treatment of public data within public institutions like the courts.

In the contemporary era, media spectacle organizes and mobilizes economic life, political conflict, social interactions, culture, and everyday life. My recently published book Media Spectacle explores a profusion of developments in hi-tech culture, media-driven society, and spectacle politics. Spectacle culture involves everything from film and broadcasting to Internet cyberculture and encompasses phenomena ranging from elections to terrorism and to the media dramas of the moment. For ‘Logo’, I am accordingly sketching out briefly a terrain I probe in detail in the book from which these examples are taken.1 During the past decades, every form of culture and significant forms of social life have become permeated by the logic of the spectacle. Movies are bigger and more spectacular than ever, with high-tech special effects expanding the range of cinematic spectacle. Television channels proliferate endlessly with all-day movies, news, sports, specialty niches, re-runs of the history of television, and whatever else can gain an audience. The rock spectacle reverberates through radio, television, CDs, computers networks, and extravagant concerts. The Internet encircles the world in the spectacle of an interactive and multimedia cyberculture. Media culture excels in creating megaspectacles of sports championships, political conflicts, entertainment, "breaking news" and media events, such as the O.J. Simpson trial, the Death of Princess Diana, or the sex or murder scandal of the moment. Megaspectacle comes as well to dominate party politics, as the political battles of the day, such as the Clinton sex scandals and impeachment, the 36 Day Battle for the White House after Election 2000, and the September 11 terrorist attacks and subsequent Terror War. These dramatic media passion plays define the politics of the time, and attract mass audiences to their programming, hour after hour, day after day. The concept of "spectacle" derives from French Situationist theorist Guy Debord's 1972 book Society of the Spectacle. "Spectacle," in Debord's terms, "unifies and explains a great diversity of apparent phenomena" (Debord 1970: #10). In one sense, it refers to a media and consumer society, organized around the consumption of images, commodities, and spectacles. Spectacles are those phenomena of media culture which embody contemporary society's basic values, and dreams and nightmares, putting on display dominant hopes and fears. They serve to enculturate individuals into its way of life, and dramatize its conflicts and modes of conflict resolution. They include sports events, political campaigns and elections, and media extravaganzas like sensational murder trials, or the Bill Clinton sex scandals and impeachment spectacle (1998-1999). As we enter a new millennium, the media are becoming ever more technologically dazzling and are playing an increasingly central role in everyday life. Under the influence of a postmodern image culture, seductive spectacles fascinate the denizens of the media and consumer society and involve them in the semiotics of a new world of entertainment, information, a semiotics of a new world of entertainment, information, and drama, which deeply influence thought and action. For Debord: "When the real world changes into simple images, simple images become real beings and effective motivations of a hypnotic behavior. The spectacle as a tendency to make one see the world by means of various specialized mediations (it can no longer be grasped directly), naturally finds vision to be the privileged human sense which the sense of touch was for other epochs; the most abstract, the most mystifiable sense corresponds to the generalized abstraction of present day society" (#18). Today, however, I would maintain it is the multimedia spectacle of sight, sound, touch, and, coming to you soon, smell that constitutes the multidimensional sense experience of the new interactive spectacle. For Debord, the spectacle is a tool of pacification and depoliticization; it is a "permanent opium war" (#44) which stupefies social subjects and distracts them from the most urgent task of real life -- recovering the full range of their human powers through creative praxis. The concept of the spectacle is integrally connected to the concept of separation and passivity, for in passively consuming spectacles, one is separated from actively producing one's life. Capitalist society separates workers from the products of their labor, art from life, and consumption from human needs and self-directing activity, as individuals passively observe the spectacles of social life from within the privacy of their homes (#25 and #26). The situationist project by contrast involved an overcoming of all forms of separation, in which individuals would directly produce their own life and modes of self-activity and collective practice. Since Debord's theorization of the society of the spectacle in the 1960s and 1970s, spectacle culture has expanded in every area of life. In the culture of the spectacle, commercial enterprises have to be entertaining to prosper and as Michael J. Wolf (1999) argues, in an "entertainment economy," business and fun fuse, so that the E-factor is becoming major aspect of business.2 Via the "entertainmentization" of the economy, television, film, theme parks, video games, casinos, and so forth become major sectors of the national economy. In the U.S., the entertainment industry is now a $480 billion industry, and consumers spend more on having fun than on clothes or health care (Wolf 1999: 4).3 In a competitive business world, the "fun factor" can give one business the edge over another. Hence, corporations seek to be more entertaining in their commercials, their business environment, their commercial spaces, and their web sites. Budweiser ads, for instance, feature talking frogs who tell us nothing about the beer, but who catch the viewers' attention, while Taco Bell deploys a talking dog, and Pepsi uses Star Wars characters. Buying, shopping, and dining out are coded as an "experience," as businesses adopt a theme-park style. Places like the Hard Rock Cafe and the House of Blues are not renowned for their food, after all; people go there for the ambience, to buy clothing, and to view music and media memorabilia. It is no longer good enough just to have a web site, it has to be an interactive spectacle, featuring not only products to buy, but music and videos to download, games to play, prizes to win, travel information, and "links to other cool sites." To succeed in the ultracompetitive global marketplace, corporations need to circulate their image and brand name so business and advertising combine in the promotion of corporations as media spectacles. Endless promotion circulates the McDonald’s Golden Arches, Nike’s Swoosh, or the logos of Apple, Intel, or Microsoft. In the brand wars between commodities, corporations need to make their logos or “trademarks” a familiar signpost in contemporary culture. Corporations place their logos on their products, in ads, in the spaces of everyday life, and in the midst of media spectacles like important sports events, TV shows, movie product placement, and wherever they can catch consumer eyeballs, to impress their brand name on a potential buyer. Consequently, advertising, marketing, public relations and promotion are an essential part of commodity spectacle in the global marketplace. Celebrity too is manufactured and managed in the world of media spectacle. Celebrities are the icons of media culture, the gods and goddesses of everyday life. To become a celebrity requires recognition as a star player in the field of media spectacle, be it sports, entertainment, or politics. Celebrities have their handlers and image managers to make sure that their celebrities continue to be seen and positively perceived by publics. Just as with corporate brand names, celebrities become brands to sell their Madonna, Michael Jordan, Tom Cruise, or Jennifer Lopez product and image. In a media culture, however, celebrities are always prey to scandal and thus must have at their disposal an entire public relations apparatus to manage their spectacle fortunes, to make sure their clients not only maintain high visibility but keep projecting a positive image. Of course, within limits, “bad” and transgressions can also sell and so media spectacle contains celebrity dramas that attract public attention and can even define an entire period, as when the O.J. Simpson murder trials and Bill Clinton sex scandals dominated the media in the mid and late 1990s. Entertainment has always been a prime field of the spectacle, but in today's infotainment society, entertainment and spectacle have entered into the domains of the economy, politics, society, and everyday life in important new ways. Building on the tradition of spectacle, contemporary forms of entertainment from television to the stage are incorporating spectacle culture into their enterprises, transforming film, television, music, drama, and other domains of culture, as well as producing spectacular new forms of culture such as cyberspace, multimedia, and virtual reality. For Neil Gabler, in an era of media spectacle, life itself is becoming like a movie and we create our own lives as a genre like film, or television, in which we become "at once performance artists in and audiences for a grand, ongoing show" (1998: 4). On Gabler’s view, we star in our own "lifies," making our lives into entertainment acted out for audiences of our peers, following the scripts of media culture, adopting its role models and fashion types, its style and look. Seeing our lives in cinematic terms, entertainment becomes for Gabler "arguably the most pervasive, powerful and ineluctable force of our time--a force so overwhelming that it has metastasized into life" to such an extent that it is impossible to distinguish between the two (1998: 9). As Gabler sees it, Ralph Lauren is our fashion expert; Martha Stewart designs our sets; Jane Fonda models our shaping of our bodies; and Oprah Winfrey advises us on our personal problems.4 Media spectacle is indeed a culture of celebrity who provide dominant role models and icons of fashion, look, and personality. In the world of spectacle, celebrity encompasses every major social domain from entertainment to politics to sports to business. An ever-expanding public relations industry hypes certain figures, elevating them to celebrity status, and protects their positive image in the never-ending image wars and dangers that a celebrity will fall prey to the machinations of negative-image and thus lose celebrity status, and/or become figures of scandal and approbation, as will some of the players and institutions that I examine in Media Spectacle (Kellner 2003). Sports has long been a domain of the spectacle with events like the Olympics, World Series, Super Bowl, World Soccer Cup, and NBA championships attracting massive audiences, while generating sky-high advertising rates. These cultural rituals celebrate society's deepest values (i.e. competition, winning, success, and money), and corporations are willing to pay top dollar to get their products associated with such events. Indeed, it appears that the logic of the commodity spectacle is inexorably permeating professional sports which can no longer be played without the accompaniment of cheerleaders, giant mascots who clown with players and spectators, and raffles, promotions, and contests that feature the products of various sponsors. Sports stadiums themselves contain electronic reproduction of the action, as well as giant advertisements for various products that rotate for maximum saturation -- previewing environmental advertising in which entire urban sites are becoming scenes to boost consumption spectacles. Arenas, like the United Center in Chicago, America West Arena in Phoenix, on Enron Field in Houston are named after corporate sponsors. Of course, after major corporate scandals or collapse, like the Enron spectacle, the ballparks must be renamed! The Texas Ranger Ballpark in Arlington, Texas supplements its sports arena with a shopping mall, office buildings, and a restaurant in which for a hefty price one can watch the athletic events while eating and drinking.5 The architecture of the Texas Rangers stadium is an example of the implosion of sports and entertainment and postmodern spectacle. A man-made lake surrounds the stadium, the corridor inside is modeled after Chartes Cathedral, and the structure is made of local stone that provides the look of the Texas Capitol in Austin. Inside there are Texas longhorn cattle carvings, panels of Texas and baseball history, and other iconic signifiers of sports and Texas. The merging of sports, entertainment, and local spectacle is now typical in sports palaces. Tropicana Field in Tampa Bay, Florida, for instance, "has a three-level mall that includes places where 'fans can get a trim at the barber shop, do their banking and then grab a cold one at the Budweiser brew pub, whose copper kettles rise three stories. There is even a climbing wall for kids and showroom space for car dealerships'" (Ritzer 1998: 229). Film has long been a fertile field of the spectacle, with "Hollywood" connoting a world of glamour, publicity, fashion, and excess. Hollywood film has exhibited grand movie palaces, spectacular openings with searchlights and camera-popping paparazzi, glamorous Oscars, and stylish hi-tech film. While epic spectacle became a dominant genre of Hollywood film from early versions of The Ten Commandments through Cleopatra and 2001 in the 1960s, contemporary film has incorporated the mechanics of spectacle into its form, style, and special effects. Films are hyped into spectacle through advertising and trailers which are ever louder, more glitzy, and razzle-dazzle. Some of the most popular films of the late 1990s were spectacle films, including Titanic, Star Wars -- Phantom Menace, Three Kings, and Austin Powers, a spoof of spectacle, which became one of the most successful films of summer 1999. During Fall 1999, there was a cycle of spectacles, including Topsy Turvy, Titus, Cradle Will Rock, Sleepy Hollow, The Insider, and Magnolia, with the latter featuring the biblical spectacle of the raining of frogs in the San Fernando Valley, in an allegory of the decadence of the entertainment industry and deserved punishment for its excesses. The 2000 Academy Awards were dominated by the spectacle Gladiator, a mediocre film that captured best picture award and best acting award for Russell Crowe, thus demonstrating the extent to which the logic of the spectacle now dominates Hollywood film. Some of the most critically acclaimed and popular films of 2001 are also hi-tech spectacle, such as Moulin Rouge, a film spectacle that itself is a delirious ode to spectacle, from cabaret and the brothel to can-can dancing, opera, musical comedy, dance, theater, popular music, and film. A postmodern pastiche of popular music styles and hits, the film used songs and music ranging from Madonna and the Beatles to Dolly Parton and Kiss. Other 2001 film spectacles include Pearl Harbor, which re-enacts the Japanese attack on the U.S. that propelled the country to enter World War II, and that provided a ready metaphor for the September 11 terror attacks. Major 2001 film spectacles range from David Lynch’s postmodern surrealism in Mulholland Drive to Steven Spielberg’s blending of his typically sentimental spectacle of the family with the formalist rigor of Stanley Kubrick in A.I. And the popular 2001 military film Black-Hawk Down provided a spectacle of American military heroism which some critics believed sugar-coated the actual problems with the U.S. military intervention in Somalia, causing worries that a future U.S. adventure by the Bush administration and Pentagon would meet similar problems. There were reports, however, that in Somalian cinemas there were loud cheers as the Somalians in the film shot down the U.S. helicopter, and pursued and killed American soldiers, attesting to growing anti-American sentiment in the Muslim world against Bush administration policies. Television has been from its introduction in the 1940s a promoter of consumption spectacle, selling cars, fashion, home appliances, and other commodities along with consumer life-styles and values. It is also the home of sports spectacle like the Super Bowl or World Series, political spectacles like elections (or more recently, scandals), entertainment spectacle like the Oscars or Grammies, and its own spectacles like breaking news or special events. Following the logic of spectacle entertainment, contemporary television exhibits more hi-tech glitter, faster and glitzier editing, computer simulations, and with cable and satellite television, a fantastic array of every conceivable type of show and genre. TV is today a medium of spectacular programs like The X-Files or Buffy, the Vampire Slayer, and spectacles of everyday life such as MTV's The Real World and Road Rules, or the globally popular Survivor and Big Brother series. Real life events, however, took over TV spectacle in 2000-2001 in, first, an intense battle for the White House in a dead-heat election, that arguably constitutes one of the greatest political crimes and scandals in U.S. history (see Kellner 2001). After months of the Bush administration pushing the most hardright political agenda in memory and then deadlocking as the Democrats took control of the Senate in a dramatic party re-affiliation of Vermont’s Jim Jeffords, the world was treated to the most horrifying spectacle of the new millennium, the September 11 terror attacks and unfolding Terror War that has so far engulfed Afghanistan and Iraq. These events promise an unending series of deadly spectacle for the foreseeable future.6 Hence, we are emerging into a new culture of media spectacle that constitutes a novel configuration of economy, society, politics, and everyday life. It involves new cultural forms, social relations, and modes of experience. It is producing an ever-proliferating and expanding spectacle culture with its proliferating media forms, cultural spaces, and myriad forms of spectacle. It is evident in the U.S. as the new millennium unfolds and may well constitute emergent new forms of global culture. Critical social theory thus faces important challenges in theoretically mapping and analyzing these emergent forms of culture and society and the ways that they may contain novel forms of domination and oppression, as well as potential for democratization and social justice.

London and New York: Routledge, 2003. 2 Wolf's book is a detailed and useful celebration of the "entertainment economy," although he is a shill for the firms and tycoons that he works for and celebrates them in his book. Moreover, while entertainment is certainly an important component of the infotainment economy, it is an exaggeration to say that it drives it and is actually propelling it, as Wolf repeatedly claims. Wolf also downplays the negative aspects of the entertainment economy, such as growing consumer debt and the ups and downs of the infotainment stock market and vicissitudes of the global economy. 3 Another source notes that "the average American household spent $1,813 in 1997 on entertainment -- books, TV, movies, theater, toys -- almost as much as the $1,841 spent on health care per family, according to a survey by the US Labor Department." Moreover, "the price we pay to amuse ourselves has, in some cases, risen at a rate triple that of inflation over the past five years" (USA Today, April 2, 1999: E1). The NPD Group provided a survey that indicated that the amount of time spent on entertainment outside of the home –- such as going to the movies or a sport event – was up 8% from the early to the late 1990s and the amount of time in home entertainment, such as watching television or surfing the Internet, went up 2%. Reports indicate that in a typical American household, people with broadband Internet connections spend 22% more time on all-electronic media and entertainment than the average household without broadband. See “Study: Broadband in homes changes media habits” (PCWORLD.COM, October 11, 2000). 4 Gabler’s book is a synthesis of Daniel Boorstin, Dwight Macdonald, Neil Poster, Marshall McLuhan, and other trendy theorists of media culture, but without the brilliance of a Baudrillard, the incisive criticism of an Adorno, or the understanding of the deeper utopian attraction of media culture of a Bloch or Jameson. Likewise, Gabler does not, a la cultural studies, engage the politics of representation, or its economics and political economy. He thus ignores mergers in the culture industries, new technologies, the restructuring of capitalism, globalization, and shifts in the economy that are driving the impetus toward entertainment. Gabler does get discuss how new technologies are creating new spheres of entertainment and forms of experience and in general describes rather than theorizes the trends he is engaging. 5 The project was designed and sold to the public in part through the efforts of the son of a former President, George W. Bush. Young Bush was bailed out of heavy losses in the Texas oil industry in the 1980s by his father's friends and used his capital gains, gleaned from what some say as illicit insider trading, to purchase part-ownership of a baseball team to keep the wayward son out of trouble and to give him something to do. The soon-to-be Texas governor, and future President of the United States, sold the new stadium to local taxpayers, getting them to agree to a higher sales tax to build the stadium which would then become the property of Bush and his partners. This deal allowed Bush to generate a healthy profit when he sold his interest in the Texas Rangers franchise and to buy his Texas ranch, paid for by Texas tax-payers (for sources on the scandalous life of George W. Bush and his surprising success in politics, see Kellner 2001 and the further discussion of Bush Jr. in Chapter 6). 6 See Douglas Kellner, From 9/11 to Terror War: Dangers of the Bush Legacy.
