What I'm listening to today: "Modular Notes 88 - ER301 Study I", mafmadmaf
This is a skewed-feeling but very carefully composed collection of beeps and tones over about six minutes. Not sure how to describe it. It speaks for itself.
One interesting thing about this composition is it's made on modular, but each of the four individual modules is digital and two are general-purpose computer modules. The modular rack here exists to be a tactile interface for software.
