The film contains several references to Seattle rock band Soundgarden. In addition to featuring their song "Jesus Christ Pose" during the opening credits, a Soundgarden poster can be seen in Spab's (Stephen Dorff's) bedroom, one of their music videos is on the television in Spab's suite, and the song "Like Suicide" by Soundgarden frontman Chris Cornell is playing on the radio in Morrow's (Jake Busey's) car.
Director Jefery Levy wanted to include material from Nirvana, particularly the song "All Apologies", on the soundtrack. Though the music was never obtained, Levy said an early cut of this movie was screened for singer Kurt Cobain, who "responded" to the film. Later, following Cobain's death, Levy said that he found the parallels between this movie and Cobain's life to be quite eerie.
