The Mars Volta was an American rock band from El Paso, Texas, formed in 2001. The band's final lineup consisted of Omar Rodríguez-López (guitar, producer, direction), Cedric Bixler-Zavala (vocals, lyrics), Juan Alderete (bass), Marcel Rodríguez-López (keyboards, percussion) and Deantoni Parks (drums). The band formed following the break-up of Rodríguez-López and Bixler-Zavala's previous band, At the Drive-In. They are known for their energetic live shows and their concept albums.
In 2009, the band won a Grammy Award in the Best Hard Rock Performance category for the song "Wax Simulacra". In 2008, they were named "Best Prog-Rock Band" by Rolling Stone magazine.
In September 2012 it was announced that the Mars Volta had entered a hiatus, with Rodríguez-López and Parks forming a new project, Bosnian Rainbows. Four months later, the band announced their breakup. Bixler-Zavala and Alderete subsequently formed a new band, Zavalaz. Rodríguez-López and Bixler-Zavala eventually reunited in 2014 for a new project, Antemasque.
