Paul Kalkbrenner (German pronunciation: [paʊl ˈkalkbrɛnɐ]) (born 1977 in Leipzig, Germany) is a German live act, producer of electronic music, and actor from Berlin. Because he breaks down his tracks into elements that are reassembled onstage, Kalkbrenner is considered a live act, as opposed to a DJ. He is most known for his single “Sky and Sand,” which sold over 200,000 copies, went platinum, and was highly charted in countries such as Belgium and Germany. He is also known for portraying the main character Ickarus in the movie, “Berlin Calling,” which ran for several years at Kino Central in Berlin.
