The Altai people live in Mongolia, China, and Russia. Here's Altai Kai (Altai Band) from the Altai Republic within Russia. For more than twenty years, the group has performed traditional music and favorite popular songs with traditional instruments, such as the stringed topshur. Their vocals come from the haunting throat singing found among the cultures of Central Asia.
Altai Kai recorded this version of "Jingle Bells" that begins with unfamiliar sounds, but soon becomes a clearly recognizable adaptation of the classic Christmas carol.
