Gwar, often stylized as GWAR, is an American heavy metal band formed in Richmond, Virginia, in 1984, composed of and operated by a frequently rotating line-up of musicians, artists, and filmmakers collectively known as Slave Pit Inc. Since the death of frontman and lead singer Dave Brockie in 2014, the collective has continued recording and performing without any of its founding artists or musicians.

David Murray Brockie was a Canadian-American musician, who was the lead vocalist of the heavy metal band Gwar, in which he performed as Oderus Urungus. He performed as a bassist and lead singer in the bands Death Piggy, X-Cops, and the Dave Brockie Experience (DBX), and starred in the comedy horror TV sitcom Holliston as Oderus Urungus. Brockie died of a heroin overdose in 2014.
