Pantera was an American heavy metal band from Arlington, Texas. Formed by the Abbott brothers, Vinnie Paul (drums) and Dimebag Darrell (guitar) in 1981, bassist Rex Brown would join in late 1981 with vocalist Terry Glaze. Looking for a new and heavier sound, Pantera had Terry replaced in 1987 with Phil Anselmo as the new vocalist. Pantera has sold around 20 million albums. 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 and thrash 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 in the Billboard 200.
