PREVIEW: "Balance"

Preview for the episode "Balance" from Season 6 of "Art in the Twenty-First Century" (2012), featuring artists Rackstraw Downes, Robert Mangold, and Sarah Sze.

In what ways can art convey equilibrium or disequilibrium? What is reality? How do artists perceive and express it? This episode features artists whose works explore the distinctions between balance and imbalance, and demonstrate that the smallest change in a line, a formal element, or a structure can be a radical proposition.

"Balance" premieres Friday, May 4, 2012 at 9:00 p.m. ET on PBS (check local listings).
