Nifelheim was a Swedish black metal band. The band was formed in 1990 by the twin brothers Erik and Per Gustavsson, under the stage names Tyrant and Hellbutcher. The band is known for their "old school" style of black metal.

Black metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, a shrieking vocal style, heavily distorted guitars played with tremolo picking, raw (lo-fi) recording, unconventional song structures, and an emphasis on atmosphere. Artists often appear in corpse paint and adopt pseudonyms.
