We all know ICP is the wicked shxt. Their shxt is some of the scariest music out there, but which track of theirs stands out as the wickedest of the wicked? Which song disturbed you deeper than any of their other stuff? It could be personal, maybe childhood fear or something scary you can relate to, or maybe its just the wickedest track you've ever heard.
For me it would have to be either "The Witch" (the whole Hell's Pit album could be this for me, but that creepy laugh loop and the song content really stuck a disturbing note with me. Plus the concept of The Witch is pretty scary in and of itself)
or "The Killing Fields" (the pace is slow, the music is creepy in a dream like way, and the lyrics are very graphic and dark. I also like the perspective from the victim's point of view rather than theirs. That really added to the realism and creep factor)
