Excellent. I've only been into it for a while, there's loads of it out there. Yat-kha are good (Albert Khuvezin's band) but you really should be listening to Huun Huur Tu first, those boys are excellent. 60 horses in my herd is one of the most necessary records ever released. Also, check out Sainkho Namchyleck (I'll check the spelling in a bit), she's got something like an 8-octave range. She's one of the most impressive singers from anywhere, she can do things with her voice that'd make Diamanda Galas wince.
