Doom are an English hardcore punk band from Birmingham whose first lineup were together from 1987 to 1990. Despite its short existence, the band is considered pivotal in the rise of crust punk, a genre of punk rock that takes influence and elements from extreme metal. They recorded for Peaceville Records and are cited as an early precursor to grindcore. Doom were also a favourite of BBC Radio DJ John Peel.

Crust punk is a subgenre of punk rock influenced by the English punk scene as well as extreme metal. The style, which evolved in the early 1980s in England, often has songs with dark and pessimistic lyrics that linger on political and social ills. The term "crust" was coined by Hellbastard on their 1986 Ripper Crust demo.
