German artist Christina Kubisch, a pioneer of sound art, began using electromagnetic induction in her installations as early as 1978. Since then she has constantly refined her practice of staging the effects of wireless electromagnetic transmissions. Cloud (2011/2017), produced on-site at the museum using thousands of feet of red electrical wire, hosts a fourteen-channel composition that visitors listen to by wearing customized headphones. These devices, developed by the artist, contain magnetic coils that receive the magnetic fields circulating in the cable loops and make them audible. As visitors move around the installation, they look at the chaotic electrical wiring suspended in the gallery but hear the prerecorded sounds programmed into different segments of the sculpture. For the work’s presentation at SFMOMA, Kubisch compiled a sequence of recordings of magnetic fields from various sites, including a security room in the basement of the museum; nearby locations such as Yerba Buena Gardens, a parking garage on Natoma Street, and Epicenter, a city-run space devoted to seismic safety; the Hoover Dam in Nevada; a power plant in Finland; server rooms in Austria, Germany, and Hong Kong; a Louis Vuitton store in Paris; and the Laboratory for Antiquated Video Systems at ZKM Center for Art and Media in Karlsruhe, Germany. These are heard alongside the electromagnetic sounds of Nam June Paik’s TV Crown (1965/1999), a work in SFMOMA’s collection, which was on view during the artist’s first site visit in preparation for Soundtracks, in the spring of 2016. This silent icon of media art provides both an interesting sonic experience within Cloud and a fitting historical reference: the work operates with audio generators, an audio amplifier, and an altered TV monitor, marking one of the first instances in which an artist employed live interaction between a sound system and an electronic image.
Cloud is not simply a didactic visualization of the physical principle of induction. On the contrary, it takes this process as a point of departure. The work stimulates live musical compositions, as the artist’s description of the work explains: “The basic idea of these sound spaces is to provide the viewer/listener access to his own individual spaces of time and motion. The musical sequences can be experienced in ever-new variations through the listener’s motion. The visitor becomes a ‘mixer’ who can put his piece together individually and determine the time frame for himself. . . . Every movement, even a slight turn of the head, results in different sequences of tones.”1
Kubisch started her series of Clouds in 2011, before the term became a Silicon Valley buzzword for a type of data storage. Uncannily, however, her participatory audio sculptures relate to these topics of storage and access, yet they do so in a theatrical way, turning visitors into active listeners who are constantly seeking to retrieve and mix new sonic impressions by bending down, lying on the floor, or simply turning their heads.

Electrical Walks San Francisco, 2017
Trained as a visual artist, musician, and composer, Christina Kubisch studied painting, flute, and piano before turning to electronic music in the mid-1970s. As an artist working predominantly with sound, she has created a unique body of performances, installations, and sculptures based on electromagnetic fields, a line of inquiry that stems from a deep urge to listen to an invisible world, here the world of electrical conduits and systems. After stumbling upon the interference of electromagnetic fields by chance in 1978, she began her most accomplished work using this phenomenon in 2004, when she produced the first in an ongoing series titled Electrical Walks. Using specially designed headphones that convert electromagnetic signals from the environment into sound, participants take a walk follow a map of “hot spots” such as ATM machines, security systems, parking stations, and electronic displays. Kubisch explains: “Every current in an electrical conductor—for example, a wire or a cable—generates an electromagnetic field. These currents can be ‘musical,’ like the signals running through loudspeaker cables; or they can come from electrical activity in the infrastructures of buildings or cities. The magnetic component of these fields is picked up by the sensor coils in the headphones. And, after amplification, these signals are made audible by the little speaker systems in the headphones.”2
Commissioned to produce a San Francisco walk for this exhibition—the artist’s sixty-fifth work in the Electrical Walks series—Kubisch selected and sequenced signals in the area around the museum that are particularly strong and sonically interesting. Each walk and each site-specific investigation adds to the artist’s typology of urban sounds. She calls the series an artistic work that is “social research” at the same time. In San Francisco, the walk covers the typical downtown scenery of commerce and new architecture, as well as overlooked and hidden nooks and niches. Kubisch’s approach could be superficially associated with a scavenger hunt, but it is more appropriately described as an “auditory dérive,”3 recalling the situationist practice of wandering the fabric of a city. John Cage’s legacy of eliminating the difference between noise and music is equally relevant: one encounters on these walks moments of noise as much as sequences that evoke minimalist or techno music.
For the artist, the magic of listening to what one cannot see can evoke a strong emotional response. She recounts the following experience, reminiscent of the nineteenth-century fascination with invisible presences and voices: “I put on my headphones during a very strong thunderstorm. There was no electricity, because all the power had gone out. But, when I recorded, I got the sounds of natural electricity, which was wonderful. The recording is so strange: very low, but very clear. At two points, you hear voices. You can’t understand the words, but you can tell that they are voices. I knew that electricity could transport voices, but I had never heard it before. It’s quite breathtaking when you hear things like that. This is nature, too—electrical nature!”
