The Mars Volta

The Mars Volta is an American progressive rock band from El Paso, Texas, formed in 2001. The band's only constant members are Omar Rodríguez-López (guitar, producer, direction) and Cedric Bixler-Zavala (vocals, lyrics), whose partnership forms the core of the band. The band's current line-up also includes founding member Eva Gardner (bass), Omar's brother Marcel Rodríguez-López (keyboards, synths, percussion), Linda-Philomène Tsoungui (drums) and Leo Genovese (keyboards, saxophone).

Known for their energetic live shows and concept albums, The Mars Volta formed following the break-up of Rodríguez-López and Bixler-Zavala's previous band, At the Drive-In. Seeking to experiment and expand their sound, Rodríguez-López and Bixler-Zavala recruited Gardner, Isaiah "Ikey" Owens (keyboards), Jon Theodore (drums) and Jeremy Ward (sound manipulation) to form The Mars Volta. The band released their debut EP, Tremulant, in 2002, with Gardner leaving the band prior to recording their debut album, De-Loused in the Comatorium. She was replaced by Red Hot Chili Peppers bass guitarist Flea for the sessions. The Rick Rubin-produced album received widespread critical acclaim upon its release in 2003.
