Feedback Plant is a sound sculpture made by Robert Schleisiek and Thilo Schoelpen. Two tubular constructions are placed on turntables. Shadows of the two rotating objects are projected onto a transparent screen in the front.
Microphones inside the tubes are in audio feedback constellation with two loudspeakers scanning the sonic environment like a radar.
This way the movement of the turntables is directly related to the sound produced. The speed of rotation changes arbitrarily and turns the sound into an random composition.
People moving around the sculpture influence the acoustic character of the work.
Feedback Plant is part of a series of audio-visual installations/sculptures using feedback to create sound.
