Burzum is a very special band. Their music is extreemly dense and complex, but at the same time, ubelivably miniamlistic. Personally I would say that Det Som Engang Var is the easiest Burzum album to get into. Songs like the title track off Hvis... or Rudgang... off of Filosoem take many listens to truly understand. I've been listening to Burzum daily for about two or three months now and I still feel like some of the songs havn't completly revealed themselves to me. However Det Som... is far more straight forward then the others, so I sugest you start there. After that take your choice between Filosofem and Hvis Lyset Tar Oss, all three are about equal in brillance, I still can't pick a favorite. Save the debut and the keyboard albums for later....
