Best of Show (IMHO): 
Tuvergen Band (Mongolian) a Mongolian fusion-folk trio. Night Two of Globalquerque!

Extra: The singer uses Khoomii, or overtone singing, a style of throat singing often very gutteral that produces a diversified harmony of multiple voice parts, including a continued bass element produced in the throat simultaneously by the singer.  I've heard Tibetan monks use this technique as a form of meditation.  The sound becomes hypnotic,
