Enslaved is a metal band from Bergen, Norway. Their style has changed over the years. Originally being an old-school black metal/viking metal act, they now perform a slightly more experimental and progressive form of black metal which has elements of 1970's progressive rock. The name was inspired by an Immortal demo track, Enslaved in Rot. Enslaved was formed in 1991, by Ivar Bjørnson and Grutle Kjellson. Joined by drummer Trym Torsson, they did their first demo in the summer of 1992.
