Burzum, especially from Det Som En Gang Var to Filosofem, brings you to another world of his creation. That's one thing I always look for in music, is being able to get lost in it, to visualize the music. There is a lot to Burzum that many people will never understand. By the way for anyone who likes where Burzum was going before jailtime and hasn't heard Drudkh yet, check them out. Especially the albums Autumn Aurora and Forgotten Legends.

Perhaps a bad example of trying to compare to Burzum but its my favorite by them.
