Mars Volta is simply seeing what they can get away with." Some band members have noted that the album wasn't as well-received as their earlier ones. In an interview with Geek Monthly, Cedrix Bixler-Zavala called Amputechture the band's "most misunderstood record." He continued, "But if we had children and they were our records, AMP would be our autistic child. We're very overprotective of it because it doesn't function in the real world but it does other things that most humans can't do. That's why we really still love it because it's elicited such a strong reaction in the fans." Track listing All lyrics written by Cedric Bixler-Zavala, all music composed by Omar Rodríguez-López.
