"Metal Up Your Ass" was recorded on November 29, 1982, at the Old Waldorf in San Francisco.The supporting band was Exodus, featuring Metallica's future lead guitarist Kirk Hammett.The band played all of its original material (nine songs) that the group had written up to that point, which included all of the songs from its previous demo "No Life 'Til Leather" and two new songs (which were later released on the "Megaforce" demo), all 9 of which would essentially be the entirety of their debut album minus Cliff's bass solo "Anesthesia (Pulling Teeth)".
