The eight-strong folksong and dance team Anda Union are Huun-Huur-Tu's successors with (Tibetan) bells on. Their songs, many of which have been handed down through their families, take the throat singing phenomenon, where the singer produces two or more notes simultaneously, into another dimension entirely. This is the Crosby, Stills, Nash & Young model, with amazing group harmonies and all the more impressive when it transpires one other-worldly chord pattern is coming from the flute player, who is playing his instrument while singing a "solo" piece.
