No strangers to unusual sound sources, Matmos narrow their focus on Ultimate Care II: Every sound comes from the duo's washing machine. Mimicking a single wash cycle, the 38-minute album begins with a spin of the dial and the sound of running water before zigzagging through polyrhythmic techno, rumbling musique concrète, and bursts of what sounds like free improv. Utilizing every method imaginable—from drumming their hands on the lid to inviting Dan Deacon to blast MIDI data at the unit—they wring a wealth of sounds out of their humble machine.
