Marduk is one of Sweden's leading Black Metal bands along with Dark Funeral. They started out being a Death Metal band with Black Metal elements, but later changed to extreme, hyper-aggressive Black Metal. The band's main theme has always been warfare and anti-Christian. The band formed in 1990 with guitarist Morgan Steinmeyer Hakansson, vocalist Andreas Axelsson, bassist Richard Kalm and drummer Joakim Grave. In 1991 they released their demo "Fuck Me Jesus" and soon after, a second guitarist was added in Devo Andersson, while Bogge Svensson replaced Kalm on bass.
