20 Jazz Funk Greats is the third studio album by British industrial music group Throbbing Gristle, released in December 1979 by the band's Industrial Records label.

Matmos is an experimental electronic music duo formed in San Francisco and currently based in Baltimore. 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. Apart from releasing twelve full-length studio albums and numerous collaborative works, Matmos is also well known for their collaboration with Icelandic singer and musician Björk, both on studio recordings and live tours. After being signed to Matador Records for nine years, Matmos signed with Thrill Jockey in 2012. The name Matmos refers to the seething lake of evil slime beneath the city Sogo in the 1968 film Barbarella.
