The first “Red Light Concert” in the heart of Stuttgarts Leonhard quarter is not merely a launch party, but also offers an improvised image-sound installation. Matthias Siegert (visuals) and Jörg Koch (sound) will arrange visual and acoustic material recorded in the neighbourhood of the gallery. In sessions of 30 minutes they present variations on a theme, which are then rerecorded and reexhibited. The varying results can be instantly viewed and then compared.
