IMMORTAL, originating from the Norwegian city of Bergen, has established itself as one of the most important black metal bands in the world. Formed by Demonaz (guitar) and Abbath (bass/vocals) in 1990, the band released its first three albums, Diabolical Fullmoon Mysticism, Pure Holocaust, and Battles In The North between 1992 and 1995. The band then released the album Blizzard Beasts in 1997. Shortly after, Demonaz was diagnosed with a shoulder injury. He continued to work with the band but stopped playing guitar live. Abbath switched from bass to guitar, and the band continued with different bassists over the years, releasing the albums At The Heart Of Winter (1999), Damned In Black (2000), and Sons Of Northern Darkness (2002). All Shall Fall was released in 2009. In 2015, IMMORTAL and former singer/guitarist Abbath parted ways. In 2018, IMMORTAL returned with Demonaz on guitar and also as the band's vocalist, and released their 9th studio album, Northern Chaos Gods, which was very well received by fans and the press. In 2022, IMMORTAL saw Demonaz release War Against All, the band's 10th studio album. The record, composed and performed by Demonaz, features session members Kevin Kvåle (drums) and Arve Isdal (bass and additional guitars).
