From his action-based performances of the 1970s which focused on his body and the viewer's relationship to it, to the technical feats of his later monumental sculptures which intervened into space, Chris Burden (1946-2015) consistently challenged material, physical and political boundaries. By doing so, he reflected on the surreal and precarious realities of contemporary life and invited the viewer to share his contemplations. Works of note include The Big Wheel (1979), Beam Drop (1984/2008/2009), Medusa's Head (1990) and Urban Light (2008).
