Immortal, from the Norwegian town Bergen, have established themselves as one of the most important black metal bands in the world. Formed by Demonaz (guitars) and Abbath (bass/vocals) in 1990 the group has issued eight trailblazing full-length slabs in their 25 plus year career. Dark, dismal, and utterly evil, it all started with their raw 1992 full-length debut Diabolical Fullmoon Mysticism which is home to such black metal blueprints as "The Call of the Wintermoon" and "A Perfect Vision of the Rising Northland."
