At the beginning of the 1990s, Rüdiger Neumann, Professor for Experimental Film at the Hochschule für bildende Künste Hamburg, made his film STEIN/LICHT. In a film seminar held in the mid-90s, he stated that experimental cinema is dead and that he could no longer make films. He no longer did make films. "What is experimental film compared to MTV? Nothing." That that is no longer necessarily true today can be easily discerned in the great variety of current experimental film productions. It was important for him to vehemently defend this stance. After withdrawing from active filmmaking, his turn to the sound studio, which he operated together with Stephan Konken, became increasingly important. His films were rarely screened. He had them shut away like the Arri 2SR.
