Formed in Arlington, Texas, by brothers Vinnie Paul and "Dimebag" Darrell Abbott, Pantera were one of the most brutal metal bands of the '90s. Rejecting their glam origins, they adopted a chugging, thrash-influenced style they called "power groove" and topped it off with singer Phil Anselmo's guttural bark. They racked up four consecutive platinum albums—plus controversy, broken bones, and a near-fatal overdose by Anselmo—before calling it quits in 2003.
