Otep is a nu metal band formed in 2000 in Los Angeles, California by Otep Shamaya. The band originally formed as a four-piece nu metal band and were invited to play Ozzfest before they had even signed to a label after Sharon Osbourne witnessed a brief part of their live performance. They've since played Ozzfest several times.
