In the growing scholarly literature on music in film, one category that remains discreetly neglected is pornography.

This is, by any qualitative standard, a major film genre. From as far afield as the UK, the US, South Africa, Australia and Finland, this collection explores the role of sound and music across a wide spectrum of pornography and its increasingly uncertain boundaries with mainstream erotica.
