Johannes Kreidler is a German composer and conceptual artist. He studied composition and music theory at the Freiburg University of Music and at the Institute of Sonology (computer music) at the Royal Conservatory of The Hague. This portrait centers on Kreidler's collage works. The pieces here represent the starting point for his musical/conceptual art and express the idea of "music with music," where he samples music and combines it with new sounds to give it new context. In order to adequately depict the diversity and visual aspects of Kreidler's work, a bonus DVD is included.
