Warthur
Burzum's final album recorded before Varg's heinous crimes landed him with a long jail sentence was recorded a few months after Hvis Lyset Tar Oss, and represents a refinement of that album's fusion of the project's black metal and ambient aspects. As well as including some pure metal extracts and a lengthly ambient piece - 25 minutes long, but for my money it deserves every second of that - the album also features several tracks which combine a dark ambient synthesiser line with Burzum's trademark buzzing wall of black metal noise.
The end result of this mixture is intoxicating, and is all the better for Varg leaving his cranky political views out of the lyrics (which, once again, revolve around extremely morbid and depressed musings on cosmology). As with much of Burzum's output, it comes recommended to anyone willing and able to separate the odious man from the wonderful music.
