Today we look at the nexus of politics and art, airing highlights of our cultural coverage from the past year featuring Alice Walker, Walter Mosley, Tony Kushner, Randy Weston, Steve Earle, Randall Robinson, Toshi Reagon, Tom Morello and others. We pay tribute to the late Adrienne Rich, Gore Vidal and Whitney Houston and mark the centennial of the birth of Woody Guthrie.
