National Socialist black metal

National Socialist black metal (also known as NSBM or Nazi black metal) is a small movement within the black metal music genre that promotes neo-Nazism, neo-fascism, and white supremacist ideologies. NSBM artists typically combine neo-Nazi imagery and ideology with ethnic European paganism, Satanism, or Nazi occultism, and vehemently oppose Christianity, Islam and Judaism from a racialist viewpoint. According to Mattias Gardell, NSBM musicians see their ideology as "a logical extension of the political and spiritual dissidence inherent in black metal". NSBM artists are a small minority within black metal. While many black-metallers boycott NSBM artists, others are indifferent or say they appreciate the music without supporting the musicians. Like Nazi punk, Nazi black metal is not seen as a distinct genre, being "distinguished only by ideology, not musical character".

NSBM artists do not always convey their political beliefs in their music, but may express their beliefs in interviews or imagery. Artists who hold far-right beliefs but do not express them in their music are not considered NSBM by many black-metallers, but they may be considered NSBM by outsiders. War and catastrophe are common themes in black metal, and some bands have made references to Nazi Germany for shock value, much like some punk rock and heavy metal bands.

The emergence of NSBM in the mid 1990s is linked with the prominent Norwegian black metal musician Varg Vikernes. After his imprisonment for church burning and murder, he developed his anti-Christian beliefs into an increasingly white nationalist and neo-Nazi form of Heathenry. The first black metal bands to have neo-Nazi lyrics and imagery were German band Absurd, and Polish bands Infernum and Graveland. In the United States, Grand Belial's Key and Judas Iscariot became involved in NSBM (the latter has since distanced themselves from the movement). As NSBM grew internationally, it started to overlap with existing White power music such as Rock Against Communism, hatecore, and the far-right faction of Oi!. The neo-Nazi record label Resistance Records, associated with the National Alliance, started releasing NSBM albums and even purchased Vikernes' label Cymophane Records. In 2012, the NSBM Asgardsrei festival was established in Moscow, Russia, and then in 2014 relocated to Kyiv, Ukraine.
