Theremin and MC202 pushed through an Overdrive pedal, layered with stretched audio made in Reason with some evangelic shortwave radio snippets.... its going to make you feel sick!
Solder together one Theremin kit, hook it up with your old Roland MC202 synth and stuff it all through a Yamaha MG8/2FX mixer, recorded with Audacity and tidied up in Sony Soundforge.
