How does memory function? Who creates history? Whether commemorative, critical or irreverent, the artists in episode two - Susan Rothenberg, Mike Kelley, Hiroshi Sugimoto and Josiah McElheny - delve into the past, transforming it and remaking it in their work. The hour concludes with an original piece of video art by Teresa Hubbard/Alexander Birchler, a unique and poetic meditation on the idea of memory. Isabella Rossellini hosts.
