Norwegian black metal is a subgenre of heavy metal music that emerged in Norway during the early 1990s. Characterized by its fast tempos, shrieking vocals, and dark, atmospheric sound, it often incorporates themes of mythology, nature, and anti-religious sentiments. Key bands in this genre include Mayhem, Burzum, and Darkthrone, which helped define its distinctive style. The scene is also known for its controversial history, including church burnings and violent incidents among musicians. The genre's aesthetic often features corpse paint and elaborate stage performances, contributing to its unique identity within the broader heavy metal community.
