What I'm listening to today: "Drone Commander", Eric Archer
E.A. is a synth designer now selling modules under the name "Rare Waves"; in this 2009 video he shows off his first creation, a knobs-only chaotic drone unit built into an ammunition cannister. Here he's running four in parallel, each moaning its own strange song with its own structure; each oscillator interrupts itself with wobbles and clicks, which in the broader choir form complex, cross-interacting rhythms.
