“No PC, no pre-recorded image, no musical instrument” is used.

All the image and sound of this work are made with the technique called “video feedback”.

Video feedback is an electronic closed-circuit process to create feedback of video signal, like feedback of electric guitar or microphone. You can make various types of feedback by “misconnection” of analogue video system, although PC can’t be used for it.

This work consists of “playing” of the video feedback noise. It doesn’t include any pre-recorded image. All the image comes from the abstract video noise which old video equipment creates by chance when performed. The image always goes out of control and never remains the same.

The sound of “Aleatoric” series is made by putting the video signal (yellow jack) directly into the sound input (red and white jack). Though some musical effectors are used, no actual musical instrument is used. No digital conversion by PC nor MIDI either, but only straight analogue connection. Therefore the video signal also becomes the sound signal. Naturally, the video and the sound completely synchronize. Actually, the video feedback creates the beat and the melody by itself.
