The recording sessions for
Group Sex took place in July 1980 at Byrdcliffe Studios in
Culver City,
California. Four songs on the album – "Wasted", "Don't Care", "Behind the Door" and "Red Tape" – were originally co-written and performed by vocalist
Keith Morris with his previous band
Black Flag. "Wasted" had appeared on Black Flag's 1979
extended play Nervous Breakdown. "Don't Care" was recorded during an early recording session for what was supposed to be Black Flag's debut studio album. After Morris left Black Flag, the tapes were shelved. Black Flag's version of "Don't Care" later appeared on the 1982 compilation album
Everything Went Black. "Behind the Door" was re-written and released as "Room 13" on Black Flag's 1981 debut studio album,
Damaged. Morris recorded and released "I Don't Care" with the Circle Jerks without crediting Black Flag guitarist
Greg Ginn, who composed the music. Black Flag responded by rewriting the lyrics, and then recording and releasing the song as "You Bet We've Got Something Personal Against You!" for the
Jealous Again 12" EP, which was also released in 1980. "Live Fast Die Young" is a reworking with new lyrics by Morris of "Cover Band", a song written and composed by Circle Jerks guitarist
Greg Hetson for his previous band,
Redd Kross, who recorded it for their 1980 EP
Red Cross. The title track was co-written by Morrison's friend
Jeffrey Lee Pierce, as a payment in exchange for Morris naming Pierce's group
The Gun Club. Some CD versions feature the album twice given its short run time. The back cover acknowledges this simply as "program repeats" at the end of the track list. ==Artwork==
