Among the many reconfigurations and experiments with the ‘medium of the exhibition’ of the 1960–1970s, Sonsbeek 71 stands as one the most audacious examples. Organized by curator Wim Beeren as an attempt to find a new curatorial language and innovative exhibition form, Sonsbeek 71 took ‘the entire country as its field of operation’, the ‘exhibition’ consisting of several works of land art, ‘information centres’, as well as pavilions dedicated to film, video, and art mediation. The ‘spatial relations’ exposed by the scale of this apparatus became the very object of Beeren’s curatorial inquiry. Focusing on projected moving images at Sonsbeek 71, this chapter discusses it on three different levels. First, it identifies the way both the film and exhibition apparatus were reconfigured and how Sonsbeek 71 functioned as an epistemology of the exhibition as medium. Second, it articulates a critique of the exhibition as a form intersecting technical, discursive, informational, and sensible elements, and shows how, in its radical expansion of the exhibition medium, Sonsbeek 71 ‘conflates media history with earth history’ (Parikka). Third, what is meant by the notion of the exhibition as ‘medium’ is discussed in light of the inflatable pavilions designed by the Eventstructure Research Group where structural films and artists’ films were projected. This eventually opens up to a critique of the informational, cybernetic epistemology of Sonsbeek 71.
