Grab your lawn chair and enjoy an evening of jazz with the New Horizons Jazz Ensemble and the Mid-Century Modern Jazz Quartet in Highland Bowl (1137 South Avenue), co-sponsored by WXXI. The New Horizons Jazz Ensemble, led by Don Sherman, will be first up. Their "big band" format features brass, reed, and rhythm sections and is part of the Eastman Community Music School. After a brief intermission, the Mid-Century Modern Jazz Quartet will take the stage. The four musicians play with subtlety, elegance, and a swinging beat–it’s all about lines and phrasing. A great summer evening of music. In the unlikely event of a downpour, the concert will be cancelled. No musicians want to risk getting their instruments wet! (No registration required.)
