This set-up mixes live 3 feedback systems.
It consists of my self-built instrument Lawaaij-masjien,(noise-machine) where a pickup needle dances on a spinning speaker, which are connected together. Thus the needle is constantly launched, and bounces back onto the speaker, like a yo-yo. It generates the trailing noise sounds.
Next to it my self-built instrument, the noise pipe. I had asked Carl (crew Stubnitz and friend) to play this instrument. It consists of a pipe with a speaker, on which a mini camera is mounted. This camera is placed a few inches away from a television, creating feedback in the TV signal. All possible colors appear, while moving the pipe along the television screen. The image signal fluctuates in voltage, and is fed directly to a speaker, (thus the video-signal is converted into a sound-signal) which in turn makes the camera move relative to the television (closer and further away because of the speaker-movements/vibrations). This creates an infinite mutual influence, which can still be adjusted by hand. It mainly generates the low tones.
As a third input I used an old-fashioned tape recorder, which without further playing a tape, only starts to feed back with the mixer. These are the helicopter-like sounds.
The concert took place in Rotterdam.
