I was unaware of what is called Mongolian throat singing until I chanced upon it through a friend’s Facebook post. I didn’t really think the style was nice but was captivated by the instruments used, particularly a two-string instrument that is played like the Chinese violin. Then a friend gave me some links to check out and I saw this video of a Mongolian throat singing band called Huun-Huur-Tu and I was blown away! You could hear a harmony, about two layers of vocals at work minimum at the same time, when they do this throat-singing. And that is amazing.
