Olve Eikemo (born 27 June 1973), better known by his stage name Abbath Doom Occulta or simply Abbath, is a Norwegian musician best known as a founding member of the black metal band Immortal. Before founding Immortal, Abbath performed with Old Funeral alongside future Immortal member Demonaz. While working with Old Funeral, he also joined Demonaz's band Amputation which later became Immortal. He also plays bass in Demonaz's eponymous project. Although he is primarily a guitarist, he is also proficient as a bassist and a drummer, having recorded all drums for Immortal albums Pure Holocaust and Battles in the North. Following his departure from Immortal in 2015, he announced that he would be forming a new band under the Abbath name. Early life Eikemo was born in Odda and grew up in Lysefjorden in Os just outside Bergen in Norway. As a young boy, he was an avid fan of hard rock band Kiss. His first heavy metal album was Creatures of the Night, which made him feel "immortal". He started his musical career with the band Old Funeral. He cites getting his first Venom video and his first Bathory album as the moment where "that was it" in his musical development. Projects Immortal Immortal's history began in 1989 as death metal band Amputation. At various times throughout Immortal's existence, Abbath was lead vocalist, bassist, guitarist, keyboardist, drummer, and lyricist, mainly due to the inconsistent line-ups they were able to put together. For a long time, however, Abbath served the band as vocalist, bassist and (studio) drummer while Demonaz played lead guitar. It was not until Horgh arrived that Immortal was able to secure a steady line-up, but problems continued. After the release of Blizzard Beasts in 1997, Demonaz was diagnosed with acute tendinitis, and was consequently forced to quit as guitarist, but remained as lyricist and band manager. They released At the Heart of Winter in 1999, this time with Abbath handling guitar and bass, with Horgh still on drums. This album marks a large shift in sound and style for the music of Immortal. In 2000 they released Damned in Black, with Iscariah on bass. Sons of Northern Darkness was released in 2002, with the same lineup. Soon after the release of Sons of Northern Darkness, Immortal ceased to exist. The break-up was not caused by tensions or problems, but was rather a mutual one between all members,
