Assault on Precinct 13 is a soundtrack by John Carpenter for the 1976 film of the same name, first released in 2003 through the French label Record Makers and reissued in 2013 by Death Waltz.

[1] The main title theme, partially inspired by both Lalo Schifrin's score to Dirty Harry and Led Zeppelin's "Immigrant Song",[8] is composed of a pop synthesizer riff with a drum machine underneath that "builds only in texture, but not thematically," according to David Burnand and Miguel Mera.

A held, high synthesizer note, with no other changes except inner frequency modulations, becomes the musical motif of the gang members, and reoccurs during certain violent acts in the film.

"[16] In early 2004, Piers Martin of NME wrote that Carpenter's minimalist synthesizer score accounted for much of the film's tense and menacing atmosphere and its "impact, 27 years on, is still being felt.

"[8] A vocal version of the theme, titled "You Can't Fight It", with lyrics and production by Kenny Lynch, was recorded by Trinidad singer Jimmy Chambers and released in the UK as a 45 on the Pye label in April 1978, but it failed to chart and is now a rare item.

[20] Despite this influence, except for a few compilation appearances,[4]: 193–195  the film's score remained available only in bootleg form until 2003 when it was given an official release on CD and LP in Europe through the Record Makers label.
