Plot: In the early 1990s, when hair metal was being sheered from the charts by grunge and earnest hard-rockers like Guns N Roses, Pantera, righteously flew the hard-edged heavy metal flag, almost single-handedly saving the genre from extinction. Formed in 1981 by brothers "Dimebag" Darrell Abbott and Vinnie Paul Abbott while still in high school, Pantera quickly developed a rabid following as hard-drinking, hard rockers in the Southwest triangle of Oklahoma, Texas and Louisiana while issuing four independent albums throughout the `80s
