It is midnight and you are standing on Invalidenstraße 43, just outside the Humboldt University. It is leaking. The recordings are squeezing their way through the bricks and tightly sealed windows. A faint earthquake makes your feet vibrate - or is it an underground subwoofer?

Some of them go for a quick smoke, hiding in the sound of traffic. A few, brave ones stay out all night in clubs and raves, mixing with the massive dark beats of Berlin's underground nightlife; a grungy, old-school recording of a Black Tern, distorted voices of spawning Cods 50 meters under the surface of a Norwegian Fjord, goats that sound strangely human, domestic cows, alligators, tigers, and lions whose voices bounce off from walls of concrete. In the background: noise from construction!!! VERY GOOD RECORDING QUALITY!!!
