Goblin were an electronic prog rock band from Italy. Originally known as Cherry Five, the band was commissioned by director and spook-master, Dario Argento to help finish compose the music for his 1975 horror masterpiece, Profondo Rosso AKA Deep Red. With the goal of creating such a beautifully goosebumped-out soundtrack, the band needed a much cooler and darker name, apparently, so they trashed the Genesis-inspired Cherry Five name and were re-born as Goblin. After Profondo Rosso, the band were then assigned to compose all of Argento's next film, a sort of ballet of horror, Suspiria!
Suspiria is both suspenseful and beautiful - a combination of traits that also appears in the soundtrack by Goblin. I'm not going to spoil the movie for you if you haven't seen it; I'm just going to say you will be in for quite a treat this Halloween season if you do see it! It's a classic and don't let the whole ballet thing fool you. A good movie can make anything watchable (plus there's really not much ballet anyways).
Here's a taste of Goblin's "Suspiria" if you haven't already familiarized yourself with this incredible track (or the rest of the soundtrack):
