You may have listened to music that could be described as bubbly. The latest album, Ultimate Care II, from electronic duo Matmos could be described as downright soapy! The 38-minute track is entirely sampled from a washing machine—to be more precise, a Whirlpool Ultimate Care II. But, this isn’t really a novelty for Matmos; the duo’s previous albums include amplified crayfish nerve tissue, freshly cut human hair, and the sounds of surgery.
