The mid to late 1980s also saw the creation and evolution of death metal, spearheaded by early bands such as [[Death]] (their early demos, when they were known as [[Mantas]], were highly influential), [[Possessed]], [[Morbid Angel]] and many others. Many early death metal bands credited [[Slayer]] as an influence, citing the relentless riffs, speed and dark lyrics which made them so popular.

The advent of Grunge in the early 90s is seen as the end of glam metal dominance. Nirvana's 'Nevermind' caused widespread public interest in alternative forms of music. [[Groove Metal]] became popular with Pantera's 'Cowboys from Hell' and Sepultura's 'Chaos AD'. The normally marginalized sub-genres of metal, that began forming in the early to mid 80s, soon enjoyed much wider exposure. [[Black Metal]], especially in the Scandinavian countries, began to see a huge rise in popularity<ref>fact</ref>. [[Marduk]], [[Mayhem]], and [[Burzum]] were see at the forefront of the early black metal scene, and continued to see popularity due to the controversies that surrounded the bands, such as Marduk's fascination with the Third Reich and anti-christian lyrical content; the murder of Mayhem's lead guitarist Euronymous by Burzum's Varg Vikernes, as well as the lyrical content and album themes of everything post 'Deathcrush'.

Death metal rapidly evolved and diversified into many different sub-genres: [[Suffocation]] are often credited with the more mid-tempo sub-genre of brutal death, while pioneers [[Atheist]] and [[Cynic]] brought strong jazz, jazz fusion and progressive elements to the genre. The Swedish death metal scene, which was originally known for a distinctive 'buzzsaw' guitar sound and strong hardcore punk influences, soon took the genre in a different direction. In particular, the Gothenburg scene produced extemely popular melodic death metal bands such as [[At the Gates]], [[In Flames]] and [[Dark Tranquillity]]. Other sub-genres of death metal include technical death metal ([[Necrophagist]], [[Origin]]), blackened death metal ([[Akercocke]]), death-doom metal (which was pioneered in the early 1990s by acts such as [[Autopsy]]), and deathcore, which mixes elements of metalcore into death metal (early [[Job for a Cowboy]], [[Whitechapel]], [[Despised Icon]]).
