Techno is dead, at least officially. In reality, electronic music and the nightlife subculture of going out—beyond social utopias and the Love Parade—have never been more creative and interesting than they are today. And they have never been so concentrated in one place: Every weekend, young people from all over Europe flock to a few kilometers along the banks of the Spree in Berlin; they arrive on budget flights and often stay until the last after-hour party almost merges into the next weekend. Tobias Rapp, a DJ himself and an intimate connoisseur of the scene, portrays the most fascinating, excessive, and secretly influential cultural scene of the capital and its protagonists: dancers and DJs, music producers and urban planners.
