“Der Klang, die Welt... was filmed in the same site as Listening to the Space in My Room, but now we hear Dieter Staehelin speaking about the place of music in his life, and we join him and Cécile Staehelin playing an Arabesque by Bohuslav Martinů. While they play, I turned the lens at certain moments to white, an open aperture”, Robert Beavers.
