September 9 to October 4, 1977. Gerd and Ulla Siepmann form the PLANSTUDIO Siepmann in 1973, which advertises its “products” with pamphlets in a sober design. The works seek to find indirect access to the complex concept of nature, one they see as existing both within and external to ourselves. They thus wok with a hyperbolic concept of nature. The following video works are shown continuously: Maulwurf; Verpuppung; Ich atme, also bin ich; Raum – Zeit – Selbsterfahrung; and Die Kraft der Natur. In addition, the video performance Verpuppung/Chrysalisation is staged. A documentary record is published for the exhibition.
