Slayer released Show No Mercy on December 3, 1983, through Metal Blade Records. Their debut featured singer and bassist Tom Araya, guitarists Kerry King and Jeff Hanneman, and drummer Dave Lombardo across ten songs, including “The Antichrist,” “Die by the Sword” and “Black Magic.” Much of the material began before the band had a record deal.
One early song helped Slayer decide where to take the others. In Metal Hammer’s 2024 oral history, Araya recalled rehearsing “Aggressive Perfector” repeatedly, then revising older originals because the band liked its direction so much. “This is the direction we’re going in,” he remembered them deciding. The track appeared on the Metal Massacre III compilation in 1983, connecting Slayer with Metal Blade before their first full-length release. That direction also developed from different interests within the group. Hanneman was getting deeper into hardcore punk while retaining his affection for metal; King remained firmly interested in metal. Their writing brought those tastes together. The Judas Priest and Iron Maiden influence remained audible, something King acknowledged when looking back on the debut.
Getting those songs recorded required money from close to home. Araya put earnings from his work as a respiratory therapist toward the album, with a loan from King’s father also helping cover the costs. The sessions took place in Los Angeles with engineer Bill Metoyer, and the band worked late at night. A recording contract had given them a route to releasing an album, but the musicians and their families were still helping pay to make it.
The practical limitations affected Lombardo’s performance. Brian Slagel told eonmusic in 2017 that Slayer wanted to record together as much as possible to retain their energy, but the small studio made the drummer’s large kit difficult to capture. His cymbals spilled into the other microphones, so the engineer asked him to record without them and add them afterward. Slagel remembered Lombardo standing in the room, waiting for each cymbal hit. The workaround got the parts recorded, although Slagel acknowledged how frustrating it had been for the drummer. For a band trying to capture the force of playing together, separating one part of the drum performance was a substantial compromise.
The finished record contained more than one approach to that early sound. “Crionics” retained a galloping rhythm associated with British heavy metal, while “Metal Storm / Face the Slayer” made room for the two guitarists’ exchanges. Alongside those passages were the speed and threatening lyrics of “Evil Has No Boundaries” and “The Antichrist.” The melodic guitar work and the more abrasive material existed together on the same debut.
Show No Mercy became Metal Blade’s best-selling release at the time, encouraging further recordings with Slayer. The band followed it in 1984 with the Haunting the Chapel EP, featuring “Chemical Warfare” and “Captor of Sin.” Their second studio album, Hell Awaits, arrived in 1985 with Slagel helping finance the recording budget, moving beyond the reliance on band earnings and family loans that had helped make the debut possible.
