Insane Clown Posse

Shock rock and theatrics are nothing new to the hard-rock world, but few had combined them with hip-hop until Insane Clown Posse came along in the early 1990s. Led by two gentlemen who hide their identities behind Kiss-like Kabuki make-up, the group has a diehard, unsurprisingly testosterone-heavy following. The band also appeal to fans of pro wrestling, a sport which often finds ICP making cameo appearances in the ring.
