The idea person of the project is Eva Fock (https://earswideopen.dk). It has made me play on bone and stone flutes and flutes made with various plants. Eva and Ingeborg make workshops with the children making instruments of natural materials that would almost also have existed in antiquity. 3 musicians, Ying-Hsueh Chen and Anders Børup and myself, come in and work a little with the children and make a walking sound concert together with the children.
