Many thanks to my brother, Owen (a.k.a. Stanley Forbes), for introducing me to the great Huun Huur Tu, who are folk musicians from the Tyva Republic.
Here they are at the Philadelphia Folk Festival in August, 2006, demonstrating “sygyt” (or “whistle”), which is one of three different Tyvan throat-singing styles. The video is courtesy of tantsev and YouTube. It’s quite amazing, I think.
