Huun-Huur-Tu - Eshten Charlyyry Berge (It's Hard to be Parted From a Friend)
I first heard Huun-Huur-Tu performing on the album "Fly, Fly My Sadness" alongside the Bulgarian Voices. Or perhaps it was on the great compilation of Tuvan music "Deep in the Heart of Tuva: Cowboy Music from the Wild East". In any event, their music made a big impression on me.
I like these guys because their music sounds like cold mountain air when you step outside early in the morning, or grass growing, or the simple and sweet longing for the company of a good friend.
