Schaltkreis WassermannPJ Wassermann playing the ARP 2600 Synthesizer

Schaltkreis Wassermann (Stella & PJ Wassermann) is one of the pioneering electronic groups of the early eighties. The album PSYCHOTRON of 1982 has become a much sought after cult object. In June 2012 it has been re-released on vinyl by Berlin label Private Records.

Schaltkreis Wassermann

Now there’s the new vinyl double album called SKW, again released by Private Berlin in a luxurious package with cyan vinyl, an A2 size poster and Schaltkreis blotters in the first 200 samples.

Before there had been a CD re-release in 2004 on hyperdisc that is still available and that contains the additional single tracks “Space Shuttle”, “Hyperspace”, “WHY” and the collage “Excursion” made out of recordings from a psychedelic studio session in the early eighties.


Schaltkreis live
The very successful premiere of the new Schaltkreis Wassermann live act happened in Lucerne, Switzerland, at Klub Kegelbahn on April 8th 2016. You can hear snippets of this concert on the top of this web page or at Soundcloud.

The next gigs were at Record Store Day in Basel vinyl store Plattfon and then in Berlin at Neuwestberlin on May 13th 2016. On all three gigs VJ Asteriza displayed her visuals – collages of old Schaltkreis graphics, fotos from the early 80ies and other trippy pictures and videos.

The new live repertoire consists of tracks from the new vinyl double album „SKW“, the Psychotron album, singles from the first period of  Schaltkreis and then some completely new music. Tracks like LUX and Hyperspace have been produced anew, partly using original samples. Generally my favorite synths from the 80ies have been used, like ARP 2600, ARP Avatar, Roland 100M and Prophet 6 (in place of the original Prophet V that is defective, unfortunately). The old tracks have partly been treated with additional 808 drums and old samples.

In my live set I play these instruments:
– the new guitar synth Boss SY-300,
– the Roland Voice-Transformer VT-3,
– the Mopho analog synth and the
– KORG Kaossillator.


Space Rock from 2008 to 2010
When Stella was still alive Schaltkreis Wassermann had a couple of live performances from 2008 to 2010, this time as a multimedia space rock live act with completely new repertoire. We played a series of international concerts, for instance at SYNCH festival Athens in 2009 and in Ibiza, Formentera and several Swiss venues. Although very successful with the live public Stella didn’t really like this new repertoire, she often said “this is not really Schaltkreis”. We had lots of arguments about this as she wanted the Schaltkreis sound to be purely synthesizers and I wanted to play guitar. But then sadly Stella with her beautiful voice and her far-out ideas passed away in 2011. So currently this live concept is in hibernation state.

New album coming
The last two years I’ve been busy getting my old analog synths back to a working state. Currently the ARP 2600, the ARP Avatar and the Roland System 100 are in great condition again and connected by control voltage to my Logic Pro production software, thanks to ExpertSleepers interfaces that deliver perfect timing. MIDI has such a terrible timing, especially when connected to MIDI/CV converters, so I’m very happy to have direct control voltage again. Only my old Prophet V still resists any attempts to get it working again, but I’m using a Prophet 6 now which has a fantastic sound, too, that comes very close to the original.

I have recorded a lot of new Schaltkreis material, mostly with my old analog synths. As I’m not a purist I also enjoy to add some software synths and effects, too. I’m not completely satisfied with the new Schaltkreis music as I find it not so easy to recreate the old SKW spirit in a completely different time but I’m confident to succeed. The live gigs will be helping me to get onto the right track again…
