Currently based in Baltimore, the duo formed in San Francisco in the mid 1990s, and self-released their debut album in 1997. Marrying the conceptual tactics and noisy textures of object-based musique concrete to a rhythmic matrix rooted in electronic pop music, the two quickly became known for their highly unusual sound sources: amplified crayfish nerve tissue, the pages of bibles turning, water hitting copper plates, liposuction surgery, and many more. These raw materials are manipulated into surprisingly accessible forms, and often supplemented by traditional musical instruments played by them and their large circle of friends and collaborators.

Their new album, Ultimate Care II, was recorded in the basement studio of their home. The album is constructed entirely out of the sounds generated by a Whirlpool Ultimate Care II model washing machine. Like its namesake, the album runs across its variations as a single, continuous thirty eight minute experience that starts with the grinding turn of the wash size selection wheel, and ends with the alert noise that signals that the wash is done.
