Pantera and Damageplan

Abbott formed Pantera in 1981 with his brother Vinnie Paul on drums. The band began in a glam metal style, but by the late '80s showed a greater influence from thrash metal acts such as Slayer, Megadeth, and Metallica, as well as traditional metal bands such as Black Sabbath, Iron Maiden, Motorhead, Venom, and Judas Priest. Pantera subsequently became a key formulator of the post-thrash subgenre of "groove" metal. It would not be until nine years after forming that Pantera saw its first piece of commercial success in its 1990 major label debut, Cowboys from Hell. Pantera's "groove" style came to fruition in its breakthrough album Vulgar Display of Power, released on February 25, 1992, which saw the replacement of the power metal falsetto vocals with a hardcore-influenced shouted delivery and heavier guitar sound. In 1994, Abbott dropped the nickname "Diamond Darrell" and assumed the nickname "Dimebag Darrell". Pantera began to suffer from mounting tensions between band members in the mid-1990s, largely due to vocalist Phil Anselmo's rampant drug abuse; in 2003, the group broke up.[7] Anselmo left the band for other projects, such as Superjoint Ritual and Down.
After a year, brothers Vinnie and "Dimebag" formed Damageplan, a heavy metal band which also used the Pantera-style groove metal sound. The Abbott brothers recruited former Halford guitarist Pat Lachman on vocals, and Bob Zilla on bass. Damageplan released its debut album New Found Power in the United States on February 10, 2004, which debuted at number 38 on the Billboard 200, selling 44,676 copies in its first week. When writing music for the new group, "Dimebag" said that "we wanted to stretch out and expand our capabilities to their fullest."[8]
Abbott was also an avid consumer of alcoholic beverages, as exemplified by his invention of a cocktail known as the "Black Tooth Grin".[9] The drink consists of one shot of "Crown Royal" whiskey, and generally with or accepted without an additional shot of Seagrams 7 whiskey, with a 'dash' of just enough Coca-Cola to darken the whiskey's color.
