Public art tends to get a bad rap, thanks to the many sculptural eyesores and boondoggles passed off as beautification projects that dot America's civic landscape.

Orridge — public art makes good on its potential to create unexpected, challenging, and thought-provoking aesthetic experiences outside of the museum or gallery space. Tonight, Anne Pasternak, Creative Time's President and Artistic Director, discusses the shifting purpose of public art and how her organization has gone about redefining it.
