This is a chilled out electronica track by Professor Chill. It features Anna Friederike Potengowski playing a replica of a 30,000 or more year old vulture bone pipe wind instrument from the French cave of Isturitz. Anna is the world's leading performer on models of these ancient archaeological finds. She is playing a model of the Isturitz pipe live in the Isturitz cave, where Professor Chill recorded her. He wrote the piece for her to play.
