At some point in my salad days I figured out that just turning on distortion and volume does not alone make music ‘heavy’; weight comes from the spaces between the notes, the timings, and that which cannot by automated. I think ‘Syntelman’s March of the Roaring Seventies’ [from Dance of the Lemmings by Amon Duul II] taught me the same thing about psychedelic music. It’s positively barren and sparse when compared to today’s hordes of knob-turning noise kiddies, but more 10th dimensional and mindbending than most ‘psychedelic’ dross.
