Four Flies On Grey Velvet - 1971 - 6/10
AKA - 4 Mosche Di Velluto Grigio

Studio drummer is stalked by unknown man in sunglasses.
Eventually, he tracks the man down, confronts him, and - oops - accidentally kills him.
Unfortunately, the percussionist is photographed by a disguised stranger.
Our hero seeks advice, doesn’t listen. His cute blonde wife wants to help him sleep, he turns a cold shoulder.
Aside from pounding his drum kit, they guys is just weak.
Killings, meanwhile, slowly swirl around the passive drummer. Friends, hired help, and closer.
Director Argento offers gorgeous visuals, and deaths are delivered with creeping tension.
Score is an imaginative mix of prog rock and Morricone, and plenty of drumming!
