Morricone’s score is like a children’s church choir gone horribly, disturbingly awry. As accompaniment to a film that stalks the foggy labyrinths of Venice, you couldn’t ask for a more perfectly haunting and off-kilter collection of songs.
Despite Morricone’s much deserved reputation, it’s probably Bruno Nicolai who deserves to be crowned king of the giallo soundtrack. He wrote quite a few. Most of them are very good. Many of them are great. All the Colors of the Dark is the best.
The score maintains this blend of offbeat styles that still manage to operate as a cohesive whole, becoming tenser and more threatening. It makes perfect sense in a film about the unreliable nature of perception.
