I think the Criterion Collection synopsis describes this film best in one sentence, "An episode of Scooby Doo directed by Mario Brava." So, with that in mind, you can imagine how strange the soundtrack must be. Its not your typical horror music at all. Then again, when do the Japanese do anything typical? Its actually light on the spooky and heavy on the slap bass. Yep, aliens came to earth and made a score based on funky slap rhythm section, flute, piano, and synth. To be honest, some of the tracks have borderline porn sounds, and I prefer to disregard the piece that sounds as though Steely Dan were scoring Saturday morning cartoons. Although, this is supposed to be trippy, so whatever. Truly bizarre music, especially when paired with watching the film.
