Black metal is an extreme subgenre of heavy metal music. Common traits include fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, blast beat drumming, raw recording, and unconventional song structure.

During the 1980s, several thrash metal bands formed a prototype for black metal. This so-called "first wave" included bands such as Venom, Bathory, Hellhammer and Celtic Frost. A "second wave" arose in the early 1990s, spearheaded by Norwegian bands such as Mayhem, Burzum, Darkthrone, Immortal and Emperor. The music of the early Norwegian black metal scene became a distinct genre.

Black metal has often been met with hostility from mainstream culture, mainly due to the misanthropic and anti-Christian standpoint of many artists. Moreover, several of the genre's pioneers have been linked with church burnings and murder. For these reasons and others, black metal is usually seen as an underground form of music. Additionally some have been linked to neo-Nazism, however most black metal fans and most prominent black metal musicians reject Nazi ideology and oppose its influence on the black metal subculture.
