I also fail to see how Elend is in any shape or form folk. Great band nonetheless, so it can never hurt to recommend them.
Ulver's Kveldssanger is still the best thing I've heard in this genre
Painful is not exactly the word I'd use to describe Sol Invictus. I find them very entrancing. But I see your point. They use noise and feedback quite a bit, so they're rather harsh on the ears.
Elend are amazingly atmospheric, but just too overblown and confusing for me personally. And they don't use drums, which is a shame.
I need to check out that DCD album.
He said in one of his posts that a lot of neoclassical music is also decent, or something along those lines; so I figured I'd recommend them.
EDIT:
What about Empyrium? Not saying Kveldssanger isn't good; I love it. But Empyrium's Where At Night the Wood Grouse Plays and Weiland are just as good, I think.
It's the vocals that trouble me. The music is quite pleasant. Agalloch's cover of Kneel to the Cross should how awesome their music could sound with a vocalist who doesn't sound like Bad Boy Bubby.
Death in June...in particular the albums Rose Clouds of Holocaust and But, What Ends When the Symbols Shatter?.
