Following the idea of sonority as a temporary ubiquitous experience, this set will focus on continuous ecosystems, impulse and feedback. While using computer and small electronic devices built for transmission and to pick up vibration it will mainly question sound as a transitory but reappearing element. (computer, amplifiers, HF-VLF signals). Paul Gründorfer is currently working on installations and interventions that deal with functional methods and question the spatial conditions. He develops process-related test structures and examines variable or unstable systems for their perceptibility and reception.
