Pantera was an American groove metal band from Arlington, Texas. They were formed in 1981 by the Abbott brothers – Vinnie Paul (drums) and Dimebag Darrell (guitar) – along with vocalist Terry Glaze. Bassist Rex Brown joined the band the next year. Looking for a new and heavier sound, Pantera replaced Glaze in 1987 with Phil Anselmo as the new vocalist. Starting as a glam metal band, Pantera released four albums during the 1980s. For their fifth album, Cowboys from Hell, released in 1990, Pantera introduced a heavier groove metal sound. Their sixth album Vulgar Display of Power, released in 1992, revealed a heavier sound than Cowboys from Hell and their 1994 release of Far Beyond Driven debuted at No.1 on the Billboard 200.
