March 26 to April 24, 1977. This remains to the present day Sonfist’s largest solo exhibition in a museum. Sonfist abandons producing a conventional cultural object and instead steps himself into the role of dialogue partner for the audience. Exploring the relationship between humans and animals, Sonfist stages a performance in a monkey cage at the Aachen Zoo in Drimborn Woods; acting in a normal human way during the whole day he spends in the cage, he provokes various reactions from zoo visitors. Wolfgang Becker films what takes place. A large abandoned rodent cave in an Aachen forest, grouted with plaster and then excavated, is presented as a sculpture in the Neue Galerie. An exhibition catalogue is published.
