#self-built

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.

In this set-up, called: Noise-Lab I am using a loudspeaker as instrument by playing with resonance. My starting point of this instrument was putting a question-mark at the objectivity of loudspeakers. In other words: What would happen if I gave a speaker a very subjective, and own specific sound, which had nothing to do anymore with the original sound signal it received. Like an analogue filter. So I used a former gas-heater, added a spring out of a truck to amplify its resonance, and made an iron frame, where all the elements were hanging like in a christmas tree, for maximum resonance. With a subwoofer the installation started to vibrate, which I expanded with sending feedback back into the system, which was picked up by microphones again.

At particular frequencies the iron started to quake and produced sounds (or noise), amplified my mics, and sometimes I added effects, to make the impact larger, controlled by self-built midifaders. With this laboratorium-like set-up (including white suit and sterile gloves) I express a sound research or a loudspeaker operation. This instrument was the forerunner of my later built "Rauschmachine".

Preparing the stage during Brug Theater festival Alkmaar in the Irish pub, for a performance with a self-built instrument

SPLASHBOX enables vibrations to become audible underwater. 2 bassins of water are put in motion by a remote controller and made audible by using underwater microphones. In my live performances I make compositions with the resonance of selected daily objects under water by adding or removing them. During this wet dance a minicamera is connected. Moving images of the soundsoup are projected on a big screen, so the audience can have a look into the source of this soundkitchen. This mini-laboratorium shows a real time research with the sounds of daily objects around us, mixed together with the sound of (under)water and very low frequencies.

The very first version of my self-developed instrument, and building the final version during an artist-in-residence project in Eindhoven.
