2. Ozzy Osbourne
While Black Sabbath brings its fair share of drama to the table, I think front-man Ozzy Osbourne takes the cake as one of the craziest performers in rock-and-roll history. Why? Well, he bit off a dove’s head during a live solo concert in 1981, causing a mass controversy, and then repeated the biting act a year later, but this time with a bat. If belting out a heavy metal tune with real animal blood dripping down your throat doesn’t classify as theatrical, I don’t know what does.
