What I'm listening to today: "Make Noise Strega, Korg nu Tekt nts-1", grumpfigrumpf
This is a lovely, brain-stem-grabbing ambient jam I return to sometimes. It's basically the epitome of drone music, because it consists entirely of an echo filter run into a second echo filter. (The Strega *does* have a vco, but it isn't on at first; instead they initially seed the feedback loop by turning the delay speed down until the bbd resolution is so low it introduces crackling.)
