Well, first of all I'll start off by saying that I ordered Burzum's Umskiptar limited edition vinyl. I feel good knowing I gave $40 to a murderer/church arsonist. (And yes, the money is going to him, not the label, because he owns the label it was released under.) It's a very interesting recitation of the Old Norse poem, Völuspá. The beginning and end are very ambient and atmospheric, perfectly setting the dramatic mood of creation (in the introduction) and destruction (in the last two songs, about Ragnarök).
Yesterday, I was on /mu/, and discovered a band called The Microphones. Nothing has made me feel more like a hipster than listening to this song:
But it's a very, very good album.
I've also started getting into Animal Collective (though I'm still very new to them). So yeah. Those are the two hipsterest bands in existence.
