Burzum - Thulêan Mysteries (Full album) 2020

you might not like the guy, or you might, I don't know. But this is pretty cool imo

wiki: 'Recorded as a soundtrack to Vikernes' role-playing game MYFAROG, the album follows the medieval/dark ambient musical style of the previous albums. Vikernes said of Thulêan Mysteries:

"Since my true passion has never been music, but actually tabletop role-playing games, I figured I should make this an album intended for that use; as background music for my own MYFAROG (Mythic Fantasy Role-playing Game)."...'
