Some of us can't get enough throat singing. Others find it not so enchanting.

Clicking on the Tuvan Music folder on the left of the screen will reveal a further choice of Tuvan music, most of which I guarrantee you is not to be found in the rapidly disappearing record stores of England's high streets — and most certainly not in the ghastly emporiums of America's malls. And I suspect, but have not ascertained, on Amazon, either UK or US.
There is something of a cult over here, at least on the west coast, over throat singing. Much of it is due, I think, to the Genghis Blues film (and subsequent album), which is marvelous and I urge you to view if you can. It's somewhat Buena Vista Social Club-like in its appeal, the redemption thing, but much funkier. Not due to the music so much as the whole social milieu. Paul Pena, the American, who travels to Tuva and wins some big festival, had a bit of an underground reputation not only as the writer of "Fly Like An Eagle," the Steve Miller hit, but as a player way back in the Haight-Ashbury. He died a few years after the filming and was obviously not well at the time, but the man was full of musical joy. Hey! You may even get to like throat singing!
