An Atari, a Memorymoog, a couple of old Rolands and some samples scooped from a Casio FZ-10M. 11 Vodka (Mix 2) has some pretty neat building blocks.
Have a good ear-swab by clicking play here. It's a remastered version of a track that originally appeared on the mid-90s album Expert Knob Twiddlers by Mike & Rich (aka µ–Ziq & Aphex Twin).
Mike's brilliant Planet Mu label is rereleasing this chunk of old electronic chunkiness. There'll be new tracks too, including one called Portamento Gosh and another called Organ Plodder. Kinda proper excited for this one.
