Side A of the Scum album was originally recorded for £50.00 at Rich Bitch studio (Birmingham, England) in August 1986: it was intended to form part of a split release with the English crossover thrash band Atavistic on Manic Ears (Bristol, England). After an extensive line-up change, the second half of Scum was recorded in May 1987 at Rich Bitch studio. The album was released as a single album through Earache in July 1987. Notably, only drummer Mick Harris played on both sides of the album.
The first pressing of the CD (1988) came as a 54-track CD including the From Enslavement To Obliteration album and four bonus tracks. In 1994, the first two albums were re-released separately. A remastered version was released on 27 January 2012.
The album cover was designed by Bill Steer's Carcass bandmate, Jeffrey Walker. The album covers came in varied colors: orange, gold, green, blue, and yellow.
