There are no less than two urban legends circulating around the world attempting to explain the origin of "Maggot Brain," though probably more. One story has Funkadelic founder George Clinton finding his brother's dead, decomposed body in a Chicago apartment. The theory that's more popular—and likely—is that, while under the influence of LSD, Clinton told guitarist Eddie Hazel to play as if he'd been told that his mother was dead (and then, as she wasn't). What emerged is one of the greatest guitar solos in music history, and sparse verbiage, even for a record rife with ideas about death.
