Aura Noir is a black/thrash metal act from Norway. Their style tends more toward old-school BM. Originating as a duet of multi-instrumentalists, Apollyon and Aggressor, Aura Noir grew into a full-scale band when Blasphemer of Mayhem joined their cause. Over the time, the band's recordings featured several notable guests, including Fenriz of Darkthrone on vocals. Soon after releasing "The Merciless" (2004) on Darkthrone's label Tyrant Syndicate, Aggressor got into an accident (fell from the roof of a four-story building in Oslo)
