May have to check out the Genghis Blues--Saw some Tibetian monks perform a few years ago, and throat singing was included. Quite amazing. And even many rows back, in a quite large auditorium, you could sense the serenity and presence of the elders. An almost palpable something that I never experienced in church when I attended as a youngin' (haven't been for a long while...).
Richard Feynman, a pretty well known physics professor from Caltech took a trip to Tuva to see throat singers and where they come from more than a few years ago. PBS broadcat a show which included this trip and the extensive hurdles overcome to make it. It's one of those very few things on TV that you keep wishing that you could have taped.
