Paul Kalkbrenner (born 1977 in Leipzig, Germany) is a German electronic musician and actor from Berlin. In early 2006, German director Hannes Stöhr, an avid fan of Paul's third album Self (2004), decided to get in contact with Kalkbrenner. His idea was to produce a film about a Berlin techno musician during the new millennium, and Paul would compose the soundtrack. In the course of their exchange, Hannes had the realization that Paul should not just contribute the music, but that he would be the perfect choice as the film's star. Without hesitation, Paul accepted the offer. They decided to title the film Berlin Calling. Berlin Calling and Paul's debut acting performance received positive reviews, and the film, thanks to its authentic depiction of the Berlin club scene and drug culture, became, slowly but surely, a cult classic. The soundtrack and especially the single "Sky and Sand" broke many sales records. The 2009 DVD release of the film brought Paul to a new, much larger audience around the world. In early 2010 Paul completed a twelve-city live concert tour throughout Europe (with over 50,000 tickets sold within just a few weeks), followed by many headlining appearances at summer festivals.
