There are several references to avant-grade singer/performance artist Diamanda Galas throughout the film:
* The character Vena Cava shares a name with an album Galas released in 1993.
* Vena's line of "Give me sodomy or give me death" is taken from the song "Confessional" off of Galas' 1991 album "Plague Mass" and is used in a very similar context.
* When Morphine disguises herself as Mallory, the soundtrack plays excerpts from Galas' 1982 recording of "The Litanies of Satan."
