UPC 743218982323

The soundtrack of Mulholland Drive was supervised by Angelo Badalamenti, who collaborated on previous Lynch projects Blue Velvet and Twin Peaks. Badalamenti, who was nominated for awards from the American Film Institute (AFI) and the British Academy of Film and Television Arts (BAFTA) for his work on the film, also has a cameo as an espresso aficionado and mobster.

Reviewers note that Badalamenti's ominous score, described as his "darkest yet", contributes to the sense of mystery as the film opens on the dark-haired woman's limousine, that contrasts with the bright, hopeful tones of Betty's first arrival in Los Angeles, with the score "acting as an emotional guide for the viewer". Film music journalist Daniel Schweiger remarks that Badalamenti's contribution to the score alternates from the "nearly motionless string dread to noir jazz and audio feedback", with "the rhythms building to an explosion of infinite darkness." Badalamenti described a particular technique of sound design applied to the film, by which he would provide Lynch with multiple ten- to twelve-minute tracks at slow tempo, that they called "firewood", from which Lynch "would take fragments and experiment with them resulting in a lot of film's eerie soundscapes."
