It was a busy week in Berlin but one of the nice surprises was a visit to Teufelsberg, a former NSA ‘listening station’ that has been abandoned since the wall came down. This small complex of buildings sits on top of an artificial mountain of rubble left over from the second world war. A group of us went to listen to something else, the space itself. Actually there were multiple spaces that included some old concrete military buildings and a series of geodesic domes, which I imagine, must have housed the surveillance equipment. The highest dome, sits at least 7 stories up, has a fiberglass shell that offers many sonic possibilities with its unique acoustic properties. The video below is composed of a few clips I filmed (in very windy conditions) while the sound is excerpted from a straight recording of a 40 minute improvisation of 5 people. Special thanks to Natalia for suggesting this and for Dusan to drive us out there in the snow.
