Here is the soundtrack to Dario Argento's 1984 film, Phenomena, starring Jennifer Connelly and the late, great Donald Pleasance. It also features Michaele Soavi, thousands of insects, a pit of decomposing body parts, and a trained chimpanzee with a straight razor. So, in other words, it's a masterpiece. The soundtrack is equally awesome, with a score by Claudio Simonetti and tracks from Iron Maiden, Motorhead, Andi Sex Gang, and more.
here is the video for the theme, performed by Simonetti, video directed by Dario Argento. It was nicely added to my dub vhs of this fine film.
