I fucking love richie hawtin. have gigs of his sets and all his plastikman on vinyl. I can't say that what I've heard is psychedilc (sp!) thou.
Or maybe my idea is different to yours. Other than that you got it spot on. He is immensly talented. Have you seen his 2hr video lecture from 2002? You can get it on http://www.themixingbowl.org He explains where Plastikman and indeed Hawtin the DJ came from, the sound, the fxs, the DJing etc...
