Over the course of a day Tim Shaw and Laurent Güdel followed their ears, they visited forests, mountains, rivers, hydroelectric plants, caves, radio broadcast towers, wind turbines, train tracks, sacred wells, man made tunnels and abandoned factories, harvesting sounds from this tangled and ever-changing soundscape. Using various listening devices they attempted to listen into the full spectrum of activity, hydrophonic, geophonic, air-pressure, electromagnetic and radio.
