Since the 1960s Dan Graham has been one of the most seminal protagonists in conceptual art. With his walk-through glass Pavilions, he places architecturally designed elements in space, thereby altering the viewer's perceptions of its surrounding. The resulting estrangement effect enables the viewer to rediscover and re-experience spatial dimensions. Among his recent projects is the commission of the Roof Garden on the Metropolitan Museum in New York which was made in cooperation with the landscape architect and ETH professor Gunther Vogt. This exhibition at the ETH is the artist's first institutional solo show in Zurich. The publication fleshes out Graham's perspective on his model-like works, in which art and architecture come together.
