Among Germany’s leading contemporary artists, Tobias Rehberger presents visually confounding objects and environments that question the ways art is defined. Playing with perception, literally and conceptually, the Golden Lion winner works across media, creating installations, sculptures, paintings, and sound and video art. “The bottom line, to put it very basically,” he has said, “is…what is art anyway?” His work can be understood as the repetitive asking of this question without the expectation of a fixed conclusion. His installations have been included in both the 50th and 53rd Venice Biennales. For the former, Rehberger presented a canopy of lamps, which could be turned on by switches located in seven different places around the world, among them a pumpkin field in Romania.
