DUSSELDORF.- The foundation of the Kunstsammlung Nordrhein-Westfalen is an art collection of the highest conceivable quality. Preceding the reinstallation of the collection in July 2010 in an area measuring more than 10,000 m² is a singular presentation in the Ständehaus of K21, one that juxtaposes key works of classical modernism with central positions of contemporary art. The galleries accommodate a series of highly divergent works, and the results range from the lively dialogue, to the quarrelsome duet, to the intimate conversation, but also include small talk, while some encounters may lead to subsequent rendezvous. Since the presentation at Grabbeplatz has always consisted mainly of paintings, and the one at the Ständehaus primarily of installation, sculptural, photographic, and video works, this exchange also takes place between two and three dimensions.
