Lives & works in Cologne (Germany)
Audio-visual artist, composer, performer Hans W. Koch works with electronic-sound produced by or taken from everyday-tools: household-electronics, hairdryers, steel wool for cleaning pots and pans or old computers. Combining these sounds in unusual ways to reveal the more hidden aspects of their functionality, he aims to transform them into instruments. Emerging music-like structures during this process are more or less a side effect of the search for the proper abuse of these objects. Simultaneously, Koch works with digital means, trying to explore their boundaries and implicit faults, in order to arrive at interactions which keep a live of their own and react in an unpredictable way to human input". His audio-visual installation ’Computermusik I - exploded view for computer-corpse’ and live electronic explores the instrumental potential of an old and out-of-service computer, not in terms of bits and bytes, but through a direct attack on the circuit board. "Signals are taken from the „legs" of the circuitry, the "working - rhythms" of the computer are transposed into the audible range by ring modulation; paths and changes in the innermost of the machine are unveiled. Because of the irreversible changes resulting from those intrusions and manipulations, it is impossible to produce repeatable results: even a short rehearsal with the chosen computer changes its inner structure to such an extent, that results on stage would be totally different. Thus, preparation means gathering experiences with the setup in order to gain a repertory of sound-finding strategies, facing an unknown computer on stage." (Hans W. Koch).
Koch exhibited twice at CCNOA. In 2002, he was invited to participate in the CCNOA experimental audio program ’Earwitness’ and presented his audio installation ’Shanty’. His exhibition in 2003 featured his audiovisual installation ’Computermusik’ involving a live ’de-construction’, it’s recording, and its subsequent screening in the CCNOA project room.
