Materials: solar panel, solar cells, radio receivers and amplifiers.
An autonomous solar energy system provides the electricity for 4 amplifiers, these are individually connected to four radio receivers playing “white noise” that are themselves powered by small solar cells.
The radios are tuned to “white noise” channels on the site = the electromagnetic waves traveling through the air of the Belziger Landschaftswiesen.
The result is an “erratic” musical composition: the changing sunlight, weather, time and visitors automatically effect both the radios and amplifiers and continually alter the four-channel composition.
