PREVIEW: "Change"

Preview for the episode "Change" from Season 6 of "Art in the Twenty-First Century" (2012), featuring artists Catherine Opie, El Anatsui, and Ai Weiwei.

How do artists respond to a world in flux? In what ways do artists act as agents of change, and what kinds of aesthetic choices do they make to express it? This episode features artists who bear witness, through their work, to transformation—cultural, material, and aesthetic—and actively engage communities as collaborators and subjects.

"Change" premieres Friday, April 13, 2012 at 9:00 p.m. ET on PBS (check local listings).
