Mayhem are a Norwegian black metal band formed in 1984 in Oslo long regarded as one of the pioneers of the Norwegian black metal scene.
The group released a demo and an EP soon after it was formed that were highly influential, and amassed a loyal following through sporadic and notorious live performances.

Their post-Aarseth material is characterised by increased experimentation. Mayhem's most recent album, Ordo Ad Chao, received the Spellemannprisen award for Best Metal Album in 2007.
