Check out Swedish "esoteric rock" act Lodge Doom, the duo of classical composer/music professor/violinist Thomas von Wachenfeldt and singer/guitarist Eric Hellman (Sunset Sinners, My Observer): http://www.myspace.com/lodgedoom
The band is currently streaming their 4-song EP "The Walpurgis session" along with two tracks off their debut full-length "Visions of dunkelheit", due out later this fall. If you dig heavy progg with folk influences, you'll probably be into this.
