Lawrence Abu Hamdan finds in a former GDR state radio station a perfect conduit for his ongoing cinematic interrogation of the political dimensions of sound. Centered on a series of court cases that used auditory or sensory evidence based on information gathered through walls, the film is staged within two soundproof booths, in which a live narrator recites witness testimonies while projected text and images create organic superimpositions. It’s an exploration of the fundamental abstractions of seeing and listening.
