The story of San Francisco blues singer, Paul Peña's, journey to the lost nation of Tuva. Peña teaches himself to throat sing in the Tuvan way, and heads off halfway around the world to compete in a throat singing competition where the prize is a horse he won't be allowed to take on the plane.
Peña, who is blind, finds himself treated with respect in Tuva for his singing and his understanding of people. He reflects on the fact that he is denied this respect back in the US, where he is just a helpless blind man.
It's a touching, fascinating story, but it skips entirely the science of (or even a cursory discussion of) what throat singing actually is. This article at Scientific American tries valiantly to explain it: Scientific American: The Throat Singers of Tuva.
The journey also follows in the spiritual footsteps of the great American physicist Richard Feynmann, who attempted to visit shortly before he died. Indeed, he got the ball rolling by wondering whatever happened to the nation he collected stamps from as a boy. More about Tuva at the Friends of Tuva. More about Feynmann at Feynmann Online.
