Show No Mercy was the debut studio album by American thrash metal masters Slayer! SNM was originally released on December 3, 1983 by Metal Blade Records. In honor of Show No Mercy's 40th anniversary, Metal Blade Records is unleashing a special edition vinyl set that includes a colored LP mastered for vinyl from the original master tapes by Patrick W. Engel at Temple of Disharmony, slipmat, poster, fliers, signing card, and an LP booklet featuring the story of Show No Mercy, written by J. Bennett. Formed in 1981, Slayer assaulted the world with a new hybrid of metal and punk - heavier, faster and darker than the rest - and set a new standard, defining not only a genre, but an attitude. Throughout Slayer's history, the band never faltered in unleashing their extreme and focused aural assault, and repudiating temptations, Slayer always chose to remain crushing and brutal, steadfastly refusing to cater to the mainstream.
