Enslaved is one of the most long lived metal bands in Norway. This year they celebrate 25 years together as a band with concert dates in Norway and Europe. The band was formed by Ivar Bjørnson and Grutle Kjellson from Haugesund, and they are still with the band. So far Enslaved have won four Spellemann awards (Norwegian Grammy), with three more nominations. Last night they celebrated their first 25 years at Rockefeller in Oslo.
