National Socialist black metal (also known as NSBM) is black metal that promotes National Socialist (Nazi) beliefs through their lyrics and imagery. These beliefs often include: white supremacy, racial separatism, antisemitism, heterosexism, and Nazi interpretations of paganism or Satanism. Some black metal bands have made references to Nazi Germany purely for shock value, much like some punk rock and heavy metal bands.
The sound itself is different from normal black metal as well, with bands often incorporating ethnic music (as expressed in folk metal and pagan metal). NSBM does not fit into normal black metal or white power music circles.
The genre was pioneered by the band Absurd in the 90's, who mixed black metal with oi! (noticeably in their early work) and political philosophies. .
