Eclectic percussionist Jerome Cooper came to Cornell “to perform, that’s under my contractual agreement. I’m not here to talk.” Or so he said at Tuesday’s American Artistic Renaissance Symposium panel, emphasizing the symposium’s performative element over its academic one. He led jam session with a glockenspiel-laden set, expertly harnessing the deep pulse of true, free jazz. Though his reputation was cemented as a soloist famous for short, rhythmic phrases, Cooper played alongside jazz legend Leroy Jenkins in the 1970’s “Revolutionary Ensemble.”
