Tom Waits did a version of this song.
It’s Waltzing Matilda, performed by a Mongolian throat singer, though really, it should be called “overtone” singing, as throat singing applies to an Inuit form of singing, which is performed differently, while overtone singing is done in places all over Asia and Europe and has a broader range of styles.
This is crazy awesome, and now I really want to learn how to overtone sing. But I know that if I wait, like, an hour (please, who am I kidding? Seven minutes), the desire will pass and I’ll want a sandwich or something instead. Really, one should be content to watch this guy Bukhchuluun Ganburged singing for ABC National Radio.
