Hans W. Koch (Cologne), is active as composer, performer and sound artist. He considers art sculpting thoughts in different materials and personally favours conceptual approaches: more thought, less material. Exploring (de)faults of soft- and hardware results in the use of computers as musical instruments in a rather physical manner. His works have been commissioned by and presented at numerous festivals and occasions both nationally and internationally. In 2008 his piece "the benchmark consort" won an award of distinction at the Ars Electronica festival in Linz/Austria. During spring semester 2007 he taught composition and experimental sound practices as visiting professor at the California Institute of the Arts, Los Angeles. Since 2012 he teaches hybrid sound composition at the Institute for Music and Media in Düsseldorf.
