The title Horizontal Boundaries refers to frame lines - the boundaries between one image and the next on a roll of motion picture film. These lines, usually hidden by the projector gate, are revealed as subject matter and as a means of dividing the screen into as many as four very wide images, stacked one above the other. They represent many places, and a few people. My intent was to find ways to allow the images to interact in ways not usually possible. The track includes some Irish fiddle solos and intense recycled dialog.
