Scum is the debut studio album by grindcore band Napalm Death, originally released in 1987. The two sides of the record were recorded by two different lineups in sessions separated by about a year; the only musician in both incarnations was drummer Mick Harris. The two sides are very different, and the two taken together serve to bridge stylistic elements of heavy metal and punk rock. While the songs on the A-side are influenced heavily by hardcore punk and anarcho-punk, the vocals and lower-tuned electric guitars on the B-side anticipate subsequent developments in extreme metal.
