There are many throat singing and overtone singing traditions around the world and also lots of modern singing with those elements. Any fans here?
Some examples:
Huun-Huur-Tu might be among the more famous tuvan groups:

Sainkho Namtchylak, also from Tuva, mixes traditional music with more modern and experimental stuff. Here seen doing something more traditional though.

Oidupaa Vladimir Oiun might be a more obscure example. His music is unusual, because the tuvan singing is accompanied by the bayan, a russian type of accordeon

A breathtakingly beautiful piece by the immensely talented mongolian singer Enkhjargal Dandarvaanchig, mostly known as Enkh Jargal.

Some western overtone singing by Christian Bollmann. A little too "new age" perhaps, but nonetheless beautiful and technically astounding.

Two clips by Christian Zehnder, a swiss singer who mixes throat singing, yodeling and other styles into something probably best described as imaginary folklore.
