Question: What band is Dimebag Darrell's brother best known for co-founding?

full_context: Document 1: Shannon Hamm: Shannon Hamm is a death metal guitarist who played in Death from 1996 until their break-up in 2001. He then joined Chuck Schuldiner's second band Control Denied, which ended with the death of Schuldiner in 2001. Before Death, he was a locally well known guitarist in the Texas underground metal scene. He was particularly good friends with "Dimebag" Darrell Abbott of Pantera and Damageplan. According to Abbott, Hamm "out shredded" Darrell in Pantera's glam metal days while Hamm was in a band named Metalstorm.
Document 2: List of songs recorded by Metallica: Metallica is an American heavy metal band formed in Los Angeles, California in 1981. The band released its debut album "Kill 'Em All" in 1983, which credited songwriting between frontman James Hetfield, drummer Lars Ulrich and guitarist Dave Mustaine, who had left before the album was recorded (bassist Cliff Burton was credited for the bass solo "(Anesthesia) – Pulling Teeth"). On the 1984 follow-up "Ride the Lightning", Burton received more songwriting credits and Mustaine's replacement Kirk Hammett was also co-credited on four songs. "Master of Puppets", released in 1986, was the last album to feature Burton, who died in a bus accident later that year.
Document 3: Kill 'Em All: Kill 'Em All is the debut studio album by the American heavy metal band Metallica, released on July 25, 1983, by the independent record label Megaforce Records. "Kill 'Em All" is regarded as a groundbreaking album for thrash metal because of its precise musicianship, which fuses new wave of British heavy metal riffs with hardcore punk tempos. The album's musical approach and lyrics were markedly different from rock's mainstream of the early 1980s and inspired a number of bands who followed in similar manner. The album did not enter the "Billboard" 200 until 1986, when it peaked at number 155, following Metallica's commercial success with its third studio album "Master of Puppets"; the 1988 Elektra reissue peaked at number 120. "Kill 'Em All" was critically praised at the time of its release and in retrospect, and was placed on a few publications' best album lists. It was certified 3× Platinum by the Recording Industry Association of America (RIAA) in 1999 for shipping three million copies in the United States. The album generated two singles, "Whiplash" and "Jump in the Fire".
Document 4: Vinnie Paul: Vincent Paul Abbott, also known as Vinnie Paul (born March 11, 1964), is an American professional drummer and producer who is best known for being a former member, and co-founder, of the heavy metal band Pantera. He is currently a member of supergroup Hellyeah. He also co-founded the heavy metal band Damageplan in 2003 with his late younger brother, Dimebag Darrell.
Document 5: Metallica discography: The following is the discography of Metallica, a Los Angeles-based metal band formed in 1981 by James Hetfield (lead vocals, rhythm guitar) and Lars Ulrich (drums). After several bassist and lead guitarist changes, the band settled on Cliff Burton and Kirk Hammett, respectively. Metallica started playing locally, releasing their first widely circulated demo, "No Life 'til Leather", in 1982. The demo caught the attention of Johny Zazula, who signed Metallica to Megaforce Records. The band released "Kill 'Em All" in 1983, and the following year they released "Ride the Lightning". After "Ride the Lightning" was released, Metallica left Megaforce and signed to Elektra Records. In March 1986, the band released its third studio album, "Master of Puppets", which was Metallica's first album to be certified gold by the Recording Industry Association of America (RIAA). While promoting the album, Burton was killed in a bus accident. Jason Newsted was hired as a replacement. The band's first release to feature the new member was "," and then followed by "...And Justice for All" in August 1988, which peaked at number six on the "Billboard" 200.
Document 6: Hellyeah: Hellyeah is an American heavy metal supergroup, consisting of Mudvayne vocalist Chad Gray, former Nothingface guitarist Tom Maxwell, bass player Kyle Sanders, guitarist Christian Brady and former Pantera and Damageplan drummer Vinnie Paul. The idea to form a supergroup originated in 2000 on the Tattoo the Earth tour, although plans were constantly put on hold due to scheduling conflicts. The summer of 2006 allowed the band to take the project seriously and record its first album. Recorded at Chasin' Jason studio in Dimebag Darrell's backyard, a self-titled album was completed in roughly one month. Released on April 10, 2007, the album entered the "Billboard" 200 at number 9, selling 45,000 copies. AllMusic reviewer William Ruhlmann stated the album is "a competent example of its genre" awarding the album three and a half stars.
Document 7: California Metal: California Metal, the first of five compilation albums released by Regency Records in the late eighties, was designed primarily to showcase the talents of the numerous unsigned Christian metal bands that had arrived on the scene following the success of Stryper. "California Metal" was quickly followed by "California Metal Volume II" (1988), "East Coast Metal" (1988), "Underground Metal" (1989) and "Underground Metal 2" (1989). As a bonus, another album released by Regency along the preceding metal line was "Classic Metal" (1990). As far as the title ""California Metal"" implies, all of the artists participating on the project come from the state of music in question and bring a variety of metal styles ranging from classic metal, melodic metal, speed metal and commercial hard rock to it. What makes "California Metal" such a noteworthy release, nevertheless, is the fact it introduced several bands that in time would become household names in the growing Christian rock, hard rock and metal music communities: "Gardian" (soon to correctly rename itself as "Guardian"), Deliverance and Neon Cross. Other artists participating on the project include Barren Cross (who debuted the previous year with its Star Song release "Rock For The King") and Mastedon which is the studio project of former Kansas vocalist John Elefante and his brother Dino. Hero was the only band appearing on the album not to go on and make a name for itself.

Like the band's next three releases, this album is musically oriented toward a glam/heavy metal sound influenced by Kiss and Van Halen, rather than the groove metal style they became famous for playing in the 1990s, starting with the release of "Cowboys from Hell". It was released on the band's own label (also called Metal Magic) and produced by Jerry Abbott (under the alias "The Eldn'"), a noted country music songwriter and producer, and father of Dimebag Darrell and Vinnie Paul, who were sixteen and nineteen years old, respectively, at the time of release.
Document 10: Far Beyond Driven: Far Beyond Driven is the seventh studio album by American heavy metal band Pantera, released on March 22, 1994 by EastWest Records. The album is Pantera's fastest-selling album. The album peaked at number 1 on the "Billboard" 200 and was certified Platinum by the RIAA. The album was also certified Platinum by the Canadian Recording Industry Association. "Far Beyond Driven" is the first album by Pantera where the band's guitarist Darrell Abbott is credited as "Dimebag Darrell", having changed his nickname from "Diamond Darrell" soon after "Vulgar Display of Power" was released. The Japanese and the "Driven Downunder Tour '94 Souvenir Collection" editions contain a bonus thirteenth track, "The Badge", a Poison Idea cover. This cover was also featured on "The Crow" soundtrack.
Document 11: Big Vin Records: Big Vin Records is an American record label based in Arlington, Texas.

Bassist Rex Brown joined the band the following year, replacing Tommy D. Bradford, who was the unofficial original. Having started as a glam metal band, Pantera released four albums during the 1980s. Looking for a new and heavier sound, Pantera replaced Glaze with Phil Anselmo in late 1986 and released "Power Metal" in 1988. With its fifth album, 1990's "Cowboys from Hell", Pantera introduced a groove metal sound. Pantera's sixth album, 1992's "Vulgar Display of Power", exhibited an even heavier sound. "Far Beyond Driven" (1994) debuted at number one on the "Billboard" 200.
Document 13: Danzig (album): Danzig is the debut album of the American heavy metal band Danzig, released in August, 1988. The album was the first release on producer Rick Rubin's new label Def American Recordings.

It remains the band's best-selling album having been certified Gold in the U.S. in 1994, and has since been certified Platinum.
