Oh shit a Burzum thread, and I thought we were going to talk about the music and not Vargs personal convictions.
Regardless, Det Som Engang Var has to be my all time favorite early black metal album. A Key to The Gate and En Ring til aa Herske are two of the coolist tracks ever to grace the recorded format (the original Key, not the re-recording version.) And you gotta admit the minimalist approach to the instrumentals is rather, haunted sounding, as well.
