Reissue of the 1983 album Show No Mercy which was the debut album by US Thrash Metal band Slayer released through Metal Blade Records. Brian Slagel signed the band to Metal Blade after watching the band perform the song "Phantom of the Opera" by Iron Maiden. The band was forced to self-finance their debut album, combining the savings of vocalist Tom Araya, who was employed as a respiratory therapist, and money borrowed from guitarist Kerry King's father. Touring extensively promoting the album, the band brought close friends and family members along the trip, who helped backstage with lighting and sound. Although criticized for poor production quality, it became Metal Blade Records highest selling release, also producing the songs "Die by the Sword", "The Antichrist" and "Black Magic", which are played at Slayer's live shows.
