6. American Horror Story
Aired: October 5, 2011 - present (FX)
Theme Song: Cesar Davila-Irizarry & Charlie Clouser "American Horror Story"
Nightmarish” is a nice way to describe the diabolical opening track from hell that chugs along during American Horror Story's morbid title sequence. The evil union of sound designer Cesar Davila-Irizarry and ex-Nine Inch Nails member Charlie Clouser sounds like bones being crushed and souls being sucked from filthy orifices by the Devil's minions. It's that scary.
