Pantera was an American heavy metal band from Arlington, Texas. The group was formed in 1981 by the Abbott brothers drummer Vinnie Paul and guitarist Dimebag Darrell along with lead vocalist Terry Glaze. Bassist Rex Brown joined the band the following year, replacing Tommy D. Bradford, who was the unofficial original. Having started as a glam metal band, Pantera released four albums during the 1980s.

With its fifth album, 1990's "Cowboys from Hell", Pantera introduced a groove metal sound. Pantera's sixth album, 1992's "Vulgar Display of Power", exhibited an even heavier sound.
