The two-day outdoor festival features 10 acts in Cain Park’s covered Evans Amphitheater, with a lineup that celebrates both the roots of jazz and the forward-thinkers in the genre today. The 42nd annual Tri-C JazzFest, presented by KeyBank, highlights include an energetic, world-infused performance by Banda Magda; extraordinary piano trios led by Christian Sands and Emmet Cohen; vocalists ranging from a 21-year-old recent Sarah Vaughan Competition winner to veteran Grammy Award-winning vocalist Catherine Russell; three thrilling horn players; and the explosive salsa of the Spanish Harlem Orchestra.
