Igor Koshkendey is a Tuvan throat singer. He's the principal creative force behind the band Chirgilchin, whom I have rather facetiously featured on Doklands once before. Sorry. He sings Testament with a springy croak, something that's rather more appealing than I am making it sound. It's pretty much exactly what you'd want a piece of Tuvan folk music to sound like, but what makes it rather special is the way that the backing singers harmonise with Koshkendey. They've got unaccented and possibly even untrained voices, and they sound like two birds trying to sing with a jet turbine. Terrific stuff from the 1998 record Music from Tuva.
