If you're into pagan folk metal kind of stuff, which I am, you might like the Russian group Arkona (Аркона). I think I found them through Eric, if I'm not mistaken, and even though there is a language barrier, I really enjoyed their most recent album, Goi, Rode, Goi!!!. They have a new video out for their song "Yarilo" that I thought I'd share here. I don't really know much about these guys, but I was really surprised when the female lead singer, Masha, started in on the growling! I love it, even though I'm not a huge fan of growling. Here is sounds so happy, though!
