Live video document of Light Bulb Music, an audio-visual performance by Michael Vorfeld, performed at 'Wabe', Berlin, June 30, 201.
"Light Bulb Music is an audio-visual performance using sounds that are generated by different light bulbs and actuating electric devices. The use of different controllers such as switches, dimmers, relays, flashers and various others leads to changes in the light and the current flow. This is made audible by a range of microphones and pick-ups. In addition, fine mechanical sounds occurring inside the light controllers are amplified and integrated into the music. The changes in the light intensity, the incandescence of the filaments and the rhythmic variety of the flickering and pulsing lights is directly transformed into a comprehensive and microcosmic electro-acoustic world of sound."
