Matmos is an experimental electronic music duo originally from San Francisco but now residing in Baltimore signed to the Matador Records label. M. C. (Martin) Schmidt and Drew Daniel are the core members, but they frequently include other artists on their records and in their performances, including notably J Lesser. Much of their work could be classified as a pop version of the musique concrète genre^{[citation needed]}. The name Matmos refers to the seething lake of evil slime beneath the city Sogo in the 1968 film Barbarella.^{[citation needed]} The name might also orginate from Swedish, literally meaning "mashed food".
