Hydra is an American Southern rock band founded in the late 1960s by Spencer Kirkpatrick (guitar), Wayne Bruce (vocals and guitar), and Steve Pace (drums). In 1977, it became a three-piece band (with Wayne Bruce now on bass) and the band broke up later that year. It released three albums, Hydra (1974), Land of Money (1975) and Rock the World (1977). In 2005, the band reunited for two shows (with Vickery on bass). A live album, Hydra: Live After All These Years was released.
