Layer 1 - 20 minute live ambient noise wall made, sped up to 68 seconds, looped 4 times to make 4'32
Layer 2 & 3 - 12.5 minute live jam with various pedals, effects and filters, sped up to 68 seconds
Layer 2 pitched up 7 semitones
Layer 3 reversed
Both looped 4 times, added to layer 1 (L1 50% left, L2 50% right)
Resulting sound sped up to 68 seconds (the first 68 seconds you hear), then the remainder uses those 68 seconds again, sped up to 16.5 seconds, then manipulated, looped, layered and 'stuff', until I got back up to 4'33" in total.
Made between July 7th and 10th 2022
