When Mark Tribe began teaching at Brown University in 2005, he was struck by the dearth of student protests on campus. A war, a controversial election. But where was the debate? So a year later, as part of an ongoing art project, Tribe began staging speeches from figures of the Civil Rights and Vietnam War era in the same places where their words were originally spoken. Tribe says their rhetoric has great relevance today. This weekend, Tribe oversaw the reenactment of a 1969 speech Angela Davis delivered in West Oakland, California, home of the Black Panthers.
