is a black metal band from Norrköping, Sweden, formed in 1991 by Morgan Steinmeyer Hâkansson in order to form the "most blasphemous band in the world". Their name is derived from Babylonian god who created the earth and sky from the body of the great dragon Tiamat. Their musical style was that of a straight-forward death metal influenced take on black metal music, but as the years progressed their style and imagery became more of a fast and intense form of black metal. The band has not played San Francisco since 2001 and due to visa issues, was forced top cancel their tour with Mayhem earlier this year. Their appearance is highly anticipated.
