Norwegian black metal band Enslaved were formed in 1991 by guitarist/keyboardist Ivar Bjørnson and bassist Grutle Kjellson; a demo titled Yggdrstll followed a year later. The group's official albums during the 1990s included 1994's Frost, 1997's Eld, and 1999's Blodhemn. In fall 2000, the band issued Mardraum, and continued over the following decade and beyond with the full-lengths Monumension (2001), Below the Lights (2003), Isa (2004), Ruun (2006), Vertebrae (2008), Axioma Ethica Odini (2010), and RIITIIR (2012). Personnel shifts have plagued the group throughout its existence; as of 2012, its membership included original members Bjørnson and Kjellson along with guitarist Arve Isdal, drummer Cato Bekkevold, and keyboardist/vocalist Herbrand Larsen.
