Alan Sondheim, with Johnson-Sondheim synthesizer, saxophone More from the archives. http://www.alansondheim.org/tube.mp3 I think this must be around 1973-1975; the background sound (which makes the pieces as far as I'm concerned) is an analog synthesizer Greg Johnson and I constructed literally from scratch (no diagrams available, only transisters and a few op amps) around 1968-69. The sound is from over- drivern voltage-controlled oscillators (VCOs), which locked into higher 'harmonics' of the system, due to their inherent instability. The driver was a very slow subsonic sound-wave. The improvisation deliberately goes nowhere (a fault of mine) and could have gone on forever.
