M.C. Schmidt and Drew Daniel formed Matmos in San Francisco in the mid 1990s. Marrying the tactics and textures of object-based musique concrète to a rhythmic matrix rooted in electronic pop music, the duo is known for their use of unusual sound sources, such as amplified crayfish nerve tissue, liposuction surgery, a cow uterus, inflatable blankets, a five gallon bucket of oatmeal and more.
