"The magnetic headphones with their built-in coils respond to electrical fields in the environment. At first I tried to filter the soft hum of the electrical wires out of the headphones. Then, in 2003, the constant increase and spread of "unwanted" electrically-produced sounds triggered a new cycle of works: Electrical Walks. With special, sensitive headphones, the acoustic perceptibility of above ground and underground electrical currents is thereby not suppressed, but rather amplified. The palette of these noises, their timbre and volume vary from site to site and from country to country. They have one thing in common: they are ubiquitous, even where one would not expect them. Light systems, transformers, anti-theft security devices, surveillance cameras, cell phones, computers, elevators, streetcar cables, antennae, navigation systems, automated teller machines, neon advertising, electric devices, etc. create electrical fields that are as if hidden under cloaks of invisibility, but of incredible presence." - Christina Kubisch.
