Watch Reverberation (1969) Official Trailer

"Reverberation began as an attempt at a portrayal, a representing of a life situation by way of film, and turned in the making of it into a presentation of the physical movement of film itself, stranding the photo-memory of persons/objects/their relationships in a cinematic force-field wherein images are offered up and simultaneously swept away by conflicting energies. Sound as it comes from a speaker has its own quality. No matter how close it comes in reproducing sound of living beings or objects, this quality is always the sound of the projector, the wires, the tubes and the speakers. This is its actuality. And it can be heard and experienced as sound, a form of energy." -Ernie Gehr
