Öffentliche Störung – Störimpulse im Öffentlichen Raum
(engl. public disturbance – glitch in public space)
a Herr B. performance
BBK-Gallery/project room, Nuremberg
21.11 & 27.11.2017
The glitch (sound impulse) is triggered by touching the end of a stereo audio-cable. The general 50 Hz hum frequency can be modified by varying the intensity of touching the plug-contacts. The human body acts as electrical grounding. Therefore the sound intensity can be enhanced by touching the ground with the barfoot feet which leads to distortion. During the performance the input signal (50 Hz hum) is modelled with sound effect machines (delay and reverb) and subsequently transformed into optical patterns via an analogue oscillograph. The patterns are filmed with a video-camera and projected with a video projector on the naked back of the performer. Therefore the skin triggers the impulse (fingers) and is at the same time projection area (back).
