He is a founding member of the black metal bands Dimmu Borgir[1] and Old Man's Child.[2] He now plays in Black Comedy and Susperia.[3] Tjodalv played guitar on the first Dimmu Borgir albums Inn i evighetens mørke and For all tid. He then switched to drumming for them on Stormblåst and continued with this until 1999. Due to his family, he left Dimmu Borgir. He was replaced by Nick Barker, formerly of Cradle of Filth.
Shortly before leaving Dimmu Borgir, he founded the group Susperia, with whom he remains active to date.
