Watch HDToday. Sven Marquardt might be the most famous bouncer worldwide. But beside standing in front of the legendary techno club Berghain in Berlin, he is also a well-known and skilled photographer. Long before the Berlin Wall came down, Marquardt portrayed the subcultural East-Berlin scene. His black and white photography illustrates it as voluptuous, laid-back, dirty and existential. Even if shot by daylight, his work is permeated by darkness, ecstasy and night.
