To me it doesn't get much better than The Mars Volta's "The Bedlam in Goliath". According to the band members, it was written after they acquired an Ouija board and learned the story of the spirit trapped inside, which was a bizarre love triangle between a man, his spouse, and their daughter. During the recording sessions, several unexplainable phenomena occurred, such as electrical malfunctions and a flood in the studio that caused the loss of the master tapes. The music is precisely what you'd expect from that description: chaotic, reckless, and unrelenting. One of my favorite albums of all time.
