I remember vividly in high-school getting my early generation Sony Walkman. Yeah I know I am dating myself. It was a marvel and expensive and desirable. Cassette tapes on the go! Well I also remember the tape I listened to over and over again on that thing when I first got it. It was The Who - Who's Next and my favorite track was Baba O'Riley. The sound on those headphones was incredible and the synth part and the start was a marvel. Despite trying to duplicate it later at various times with certain tools, I never could. Now fast forward 2009 and I get my first Modular and what happens, this track just opens up to me and becomes clear because I am using a tool with the same limitations as what Pete used. The limitation is that it's a mono-synth with certain note priority, so when you play a base pattern, then play notes over that between the base notes, you get the signature interference pattern. Add to that, some real analog oscillators and filters and envelopes and voila!
Now all the sequencing including drums, drum fills, bass, piano and the synth lines are done using SevenUpLive on the Monome. They are all laid down in one pass with no edits as I like to do. It's not a complete track but an experiment in conjuring the past.
