Guitarist/vocalist for Immortal. Also involved in other projects such as I (lyricist for Between Two Worlds) and Perfect Visions (vocalist).

Harald Nævdal, born 6 July 1970, known as Demonaz Doom Occulta, or most widely known simply as Demonaz, is most recognized as the guitarist and chief lyricist for the Norwegian black metal band Immortal.

In Immortal, he is known for his lyrics which, unconventionally for black metal, focus on icy landscapes and a fictional land called Blashyrkh. The story of Blashyrkh is gradually told throughout Immortal's albums. When writing lyrics he often takes long walks in the Norwegian countryside near his hometown of Bergen for inspiration. He was known for his simplistic but extremely fast guitar parts which were always based around power chords. With Abbath, he formed the core of Immortal until 1997, with members fluctuating otherwise and little stability until Horgh joined the band in 1997.

Demonaz played guitar on the albums Diabolical Fullmoon Mysticism, Pure Holocaust and Battles in the North, with his last musical contribution to Immortal being the 1997 album Blizzard Beasts. That same year, he was diagnosed with acute tendinopathy, and could no longer play guitar at the speed required for Immortal. Instead, he continued to write lyrics for Immortal and often took the role of manager. After having surgery to correct his tendinitis in 2013, he was able to play guitar again and has returned to that role in the band since Abbath's departure.

Demonaz has appeared in all of Immortal's music videos, including the music video for All Shall Fall, which was released in September 2010.

Demonaz has started a band called DEMONAZ where he is the vocalist. The band also includes most of the members of the band I. He wrote the lyrics for the I album Between Two Worlds. He has released his debut album, March of the Norse, in April/May 2011.

On 31 May 2016, Demonaz was officially announced as Immortal's new lead singer following the departure of Abbath in 2015. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
