Schaltkreis Wassermann was a pioneer group of electronic music. Founded in 1979 by Stella & PJ Wassermann (who still work together with several projects) Schaltkreis Wassermann featured a minimalistic approach that was dictated by the available means:
* 1 ARP 2600 Syntheseizer,
* 1 ARP Avatar guitar synthesizer
* 1 Roland 100M modular synthesizer
* and 1 Sequential Circuits Prophet V synthesizer,
all kept together by the Roland MicroComposer MC4 that was capable of playing four simultaneous monophonic synths. Tape recording was done with a TEAC 4track and later with an Otari 8track tape machine.

It was a great and very psychedelic time. Stella & PJ spent days, weeks and months in their studio exploring sound and consciousness resulting in PSYCHOTRON a ground breaking album in 1981 showcasing a lot of what was to become mainstream in electronic music and then some.

PSYCHOTRON was sold all over the world as a vinyl album and made it to numer 7 of the British synthesizer charts in "Melody Maker". Check out the sounds.
