<human>: Background: Pantera was an American heavy metal band from Arlington, Texas. The group was formed in 1981 by the Abbott brothers - drummer Vinnie Paul and guitarist Dimebag Darrell - along with lead vocalist Terry Glaze. Bassist Rex Brown joined the band the following year, replacing Tommy D. Bradford, who was the unofficial original.
Context: Shortly after Power Metal was released, "Diamond Darrell", as he was then known, auditioned for Megadeth's vacant guitarist slot, and was invited to join the band. Darrell insisted his brother, bandmate Vinnie Paul, be included, but because Chuck Behler was still in the band at the time, Darrell declined and Dave Mustaine instead decided on Marty Friedman. The Abbott brothers refocused their attention on Pantera, and in 1989 they were given their first shot at commercial success. 1989 was also when the band formed their relationship with Walter O'Brien at Concrete Management (the management arm of Concrete Marketing), who remained their manager until they disbanded in 2003.  After being turned down "28 times by every major label on the face of the Earth", Atco Records representatives Mark Ross and Stevenson Eugenio were asked by their boss Derek Shulman, who was interested in signing Pantera, to see the band perform after Hurricane Hugo stranded them in Texas. Ross was so impressed by the band's performance that he called his boss that night, suggesting that Pantera be signed to the label. Atco Records accepted, and at the close of 1989, the band recorded its major label debut at Pantego Studios.  Released on July 24, 1990, and produced by Terry Date and Pantera, Cowboys from Hell was another leap into heavier territory. Pantera showed a more extreme style on this outing, leaving behind its glam metal influences in favor of mid-tempo thrash metal dubbed "power groove" (groove metal) by the band. Although Anselmo still used Rob Halford-influenced vocals, he also adopted a more abrasive delivery. Darrell's more complex guitar solos and riffs, along with his brother's faster-paced drumwork were evidence of the band's extreme transformation. The album marked a critical juncture in the band's history. Many fans, as well as the band itself, consider it Pantera's "official" debut. Cowboys included the tracks "Cemetery Gates", a brooding seven-minute piece that focuses on death and religion, and the thrashing title track, which gave the band members their nickname and asserted their raucous personality and style.  So began the Cowboys from Hell tour alongside thrash acts Exodus and Suicidal Tendencies. In 1991, Rob Halford performed with the band onstage, which led Pantera (along with Annihilator) to open for Judas Priest on its first show in Europe. They also opened for bands like Fates Warning, Prong, Mind over Four and Morbid Angel, and co-headlined a North American tour with Wrathchild America. The band eventually landed a billing for "Monsters in Moscow" with AC/DC and Metallica in September 1991, where they played to a crowd of over 500,000 in celebration of the new freedom of performing Western music in the Soviet Union shortly before its collapse three months later. The band was often found at the Dallas club "the Basement", where the band shot the videos for "Cowboys from Hell" and "Psycho Holiday". Pantera's 2006 home video compilation 3 Vulgar Videos from Hell features performances of "Primal Concrete Sledge", "Cowboys from Hell", "Domination", and "Psycho Holiday" from the show in Moscow.
