The preeminent metal band of the early to mid-'90s,Panteraput to rest any and all remnants of the '80s metal scene, almost single-handedly demolishing any notion that hair metal, speed metal, power metal, et al., were anything but passé. Loathe to admit it, the Texas band had in fact been one of those '80s metal bands, releasing fairly unsuccessful (and later disowned) glam-inspired music throughout much of the decade. The about-face came with the addition of vocalistPhil Anselmo, and the key turning point was the band's major-label debut,Cowboys from Hell(1990).Pantera's mainstream breakthrough came next withVulgar Display of Power(1992), their second major-label album, which thrust the band to the forefront of the metal scene, alongside such veteran bands asMetallica,Megadeth,Slayer, andAnthrax, as well as fellow up-and-comersSepulturaandWhite Zombie. By the timePanteraunleashedFar Beyond Driven(1994), after two long years of touring, they were the most popular metal band in the land: the new album debuted atop the Billboard Top 200 as its lead single, "I'm Broken," was getting massive airplay.At the height of their popularity and influence,Panterabegan to self-destruct. Less than two months after the release ofThe Great Southern Trendkill(1996) -- an album ridden with allusions to drug abuse and personal destruction --Anselmooverdosed on heroin after a homecoming concert in Texas, and as tensions rose between him and his fellow bandmembers, he began engaging with a growing list of side projects that kept him away fromPantera. A live album,Official Live: 101 Proof(1997), was compiled for release when it became evident that no new studio album was forthcoming any time soon. One final studio album did result,Reinventing the Steel(2000), but that was more or less it for the briefly reunitedPantera. The bandmembers once again went their sperate ways, forming such bands asDamageplan,Down, andSuperjoint Ritual.The end ofPanterathen became official on December 8, 2004, when guitaristDimebag Darrellwas murdered on-stage by a deranged fan. This much-publicized murder shone the spotlight back onPanterafor an extended moment, and amid all of the emotional outpouring and tributes, a consensus arose: in retrospect, there was no greater metal band during the early to mid-'90s thanPantera, who inspired a legion of rabid fans and whose oft-termed "groove metal" style bucked all prevailing trends of the day -- from hair metal and grunge to nu-metal and rap-metal -- and remains singular to this day, as defined by the vocals ofAnselmoas it is by the guitar ofDimebag.
