The final three panelists of this anniversary Chautauqua season took to the Amphitheater stage Friday for a capstone conversation about the power of art to unite. While this was each speaker’s first time sharing the platform together, individually, they are no strangers to the Chautauqua stage. In fact, each speaker has been working double duty this week — performing, lecturing, preaching and acting — highlighting this trio’s multidisciplinary talents and commitment to cultural advocacy.
