In this two-channel video installation a pair of shots looking back off the rear of a bicycle slowly move through a long pedestrian overpass in East Berlin. The overpass crosses the space of a former cattle grounds and abbatoir and leads to a modernist highrise complex. Taking nearly ten minutes to complete each crossing, the images shift slowly between these twin architectural artifacts of the DDR two parts of a physical history that is gradually being erased. The cattle grounds under the overpass had already been razed at the time the video was shot, the overpass itself was torn down a few months afterwards. The title, Double Back, refers at once to the two rearward shots, to the process of perpetually retracing the routes that the shots take, and, more obliquely, to the parallel histories of East and West that continue to inform the culture of Berlin and shape its public space.
