A torch flashed at a square panel standing vertically on the floor, produces drum rhythms which vary depending on the area onto which the light is projected. Nine different close-up of ears are depicted on this photographic panel. Each ear becomes visible by means of a light box mechanism, whenever the flashlight points at it. A corresponding percussion arrangement is then produced by a digital drum module. The effect is a bigger than life size drumset into which the drum sticks are replaced by a torch light.
