In 2015, its 25th year, the Academy of Media Arts Cologne invited back the people who have built it up and stamped their mark on it over many years. What lead them to becoming part of the KHM? What in particular occupied them, moved them and kept them alive as artists, filmmakers or theoreticians at the KHM? Each one of them has, with their spirit and their imagination and from their respective artistic, theoretic and philosophic perspectives, brought the Academy of Media Arts Cologne into being. Is the interaction of these various perspectives the sound of the KHM? Personal narrative is a central concern of the series.
