The Jazz Institute of Chicago has put together a half-dozen free jazz concerts, beginning tonight at 6:30 PM in Millennium Park's Pritzker Pavilion, and closing on 27 August with a performance by the acclaimed Chicago Jazz Philharmonic. You can't go wrong with any of these concerts, which--aside from featuring local jazz greats like Dee Alexander and Von Freeman--also open with performances by Chicago's NEXT jazz generation: the likes of the South Shore Youth Jazz Ensemble, Gallery 37 After School Matters Jazz Band, and the Jazz Links Ensemble. Individual concerts are listed in Slowdown; click here for a complete schedule. AND THERE'S MORE: If you mosey over toward the BP Bridge starting around 7:30, volunteers from Adler Planetarium will share their telescopes so you can get a good look at the moon and nearby planets.
