Interference Patterns

Interference Patterns is a 13 minute A/V work that explores the electromagnetic fields emitted from modified cathode ray tube (CRT) televisions. The magnetic fields surrounding the TV are navigated by the performer using electromagnetic pickups, and the audio output of these are then fed directly back into the TV’s coil, creating a feedback loop. The energies are constantly being transformed from electromagnetic waves, to visual patterns, to analogue audio signals, and back again. There are times when the TV feeds back to itself in a similar way to a mic and PA system. There are no other audio sources and the sound is presented in its raw state.
