In the courtyard of Schloss Eggenberg, the artist collective OchoReSotto proved that change is often the only constant. In the interplay of history, present and future, everything is in flux – especially our perception. In everyday life, as here in the castle courtyard, we believe we can take in the world as it actually is. But the exact opposite is the case: if we change the angle or the view, the mood or the perspective, everything appears different. This is the essence of A.D.D.I.T.I.V.E., an intervention resembling a luminous kaleidoscope. Starting from a light source, geometric shapes and abstract structures were thrown into the room, encountering reflective bodies that reflect parts of the light back and allow others to pass through, thus creating different versions of the same content on the historic walls of the castle. In this way, you perceived what was presented to your own eyes in one place and thought you understood it. If you moved further into the installation, the parts of the reflection or the transmitted light and thus the luminous forms changed again. If you kept moving, the inner courtyard never seemed the same as before. It resembles an addition of sensory impressions: always further, always different.
The sound for A.D.D.I.T.I.V.E. was composed by Josef “Seppo” Gründler. The sounds recorded on site were distorted, alienated, expanded and repeated. The grotto in the courtyard of the castle was reflected acoustically, synthetic sounds seem to crumble. Using a quadraphonic audio setup, the sound moved throughout the courtyard – unfolding just as expansively as the light and thus becoming the acoustic counterpart to the visual intervention.
