Hellyeah is a heavy metal supergroup, consisting of Mudvayne vocalist Chad Gray and guitarist Greg Tribbett, Nothingface guitarist Tom Maxwell, Damageplan bassist Bob Zilla, and former Pantera, Rebel Meets Rebel and Damageplan drummer Vinnie Paul. The idea to form a supergroup originated in 2001 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. During an interview for the January 2009 issue of Revolver magazine, Vocalist Chad Gray revealed there may be hint of Hellyeah in the forthcoming Mudvayne album, with a tentative release date of 2009.

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 8, 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. A week after the album's release, original bassist Jerry Montano left the band to what was described as "personal reasons on both sides". Damageplan bassist Zilla replaced him, and the band released a DVD titled Below the Belt on November 13, 2007.
