In one of his first forays into big-budget Hollywood, Ennio Morricone handed in one of his weirdest, eeriest scores - Rolling Stone (top 35 greatest horror soundtracks). From the beautiful to the absolutely demented, while still playing in the same sandbox. Once you get to the deranged Satanic prog-rock of "Magic And Ecstasy," it hits you: this is the craziest we've ever heard Morricone. And it's amazing. 

"I like the first Exorcist, because of the Catholic guilt I have, and because it scared the hell out of me; but The Heretic surpasses it." - Martin Scorsese
