Dario Argento is no stranger to vivid soundtracks (an old co-worker had to turn off Suspiria because it was, in his words, "too loud!"), but former Rolling Stones bassist Bill Wyman and his long-time musical collaborator Terry Taylor delivered one of the most effective cues for any Argento film with their track "Valley", composed for 1985's oft-overlooked grim fairy tale, Phenomena (a.k.a. Creepers). That's a pretty high honor when you're in the company of a soundtrack catalog that includes compositions by progressive rock fiends Goblin and the maestro of Italian film music himself, Ennio Morricone...even more impressive for a subdued cue that leads off a soundtrack dominated by heavy metal tracks.
During the film's opening scene, "Valley" wastes no time establishing the mood and the doom of Phenomena's introductory victim as its cascading lead synth "horn" evokes a chilling alpine loneliness amidst great spaces and a melancholy, hunted vulnerability. Bill Wyman seems committed to match the piece's level of creepiness with his performance in an accompanying though unlikely music video/making-of-doc crafted by Phenomena's first assistant director, Michele Soavi:
Wyman and Taylor reprise the theme later in the movie with a more driven though less haunting jam never released on the official soundtrack:
