He began writing music in 1991, together with Fafnir and Glaurung for a project called Troll. Fafnir and Glaurung soon left the band, but Nagash continued Troll as a solo project, playing guitar and keyboard. Wanting to be in a band and "express himself on all levels", he founded the band Covenant together with Amund Svensson in 1993. (However, after having released two albums, they had to change the name to The Kovenant due to a Swedish band already called Covenant).
Gaining a good reputation in the black metal scene, Nagash was recruited as bass player for Dimmu Borgir in 1996. In 1999, he left Dimmu Borgir to concentrate on his career with The Kovenant. At the same time, he changed his stage name to Lex Icon in order to reflect the artistic direction The Kovenant had taken.
From the beginning of 2008, he recruited a full lineup for his former solo project, Troll. Their latest album Neo-Satanic Supremacy has been released in early 2010 through Napalm records.
