A song to shake something loose (2:22)

During our interview you mentioned the binaural audio theater piece The Encounter by Simon McBurney. I can remember LOVING that sonic experience but cannot for the life of me remember any specifics of what the actual audio was. Now, when I think back on the show, all I remember is this sense of confronting something that’s dark and terrifying, something ancient and powerful that comes from dirt and sweat and trees. For reasons that might make sense when you hear this song, the sonic landscape my mind has laid on top of my memories of the performance are of the Bulgarian State Radio’s All Female Choir, specifically this song from their album Le Mystere Des Voix Bulgares.
