This was perhaps one of the first non-Spaghetti Western Morricone soundtrack that I discovered and it remains one of my favorites. The title track is a stirring, swelling masterpiece. The rest of the disc contains the type of experimental noise collages featured in most of Morricone’s giallo scores, but, in this case, they’re grounded and grooved out with rhythmic drums and funky bass lines. The style plays well with the film’s theme of killer hippies and drugged out parties. There is a lot of variety here and I would rank it as one of Morricone’s best, or, at the very least, the best example of his music in a thriller.
