As with 2013's School Daze, it takes its name from a real 1980 porn film, released by L.A.'s Fox Studio, that Cowley soundtracked.
Muscle Up is the second of two releases compiling this work, spanning time spent as a student at the City College of San Francisco to the period shortly before his death in 1982, when he scored his final smashes with Sylvester, Paul Parker, Loverde, and other Bay Area acts. Yet unbeknownst to even most of his disco fans, Cowley also created synth compositions in the even-more-underground medium of gay porn.
