For its fifth YEAR the Hyde Park Jazz Festival expands to two days and features 16 venues hosting more than 40 shows this Saturday and Sunday (9/24-9/25). Saturday's performances begin at 1 PM and culminate in a midnight jam session led by Dee Alexander at the U. of C.'s Mandel Hall (1414 E. 59th). Notable acts include the Tomeka Reid Trio in the galleries of the Oriental Institute Museum (1155 E. 58th), the Orbert Davis Quintet featuring Terisa Griffin at the James W. Wagner Stage (on the Midway Plaisance between Ellis and Woodlawn), the Fareed Haque Trio with Tony Monaco at the International House's Assembly Hall (1414 E. 59th), the Maggie Brown Quartet at Court Theatre (5535 S. Ellis), and the Don Byron New Gospel Quintet at Mandel Hall. On Sunday the music starts at 1 PM and happens exclusively on the James W. Wagner stage; headliner first, the lineup is Calje with Ricky Luis, the Corey Wilkes Sextet, Nicole Mitchell & the Black Earth Ensemble, the Ari Brown Quintet, and Tatsu Aoki's Miyumi Project. On both days the Midway Plaisance also hosts a family tent that features kid-friendly music, dancing, costumes, and face painting. On Saturday in the Coulter Lounge of the International House, Michael Phillips of South Side Projections presents Reel Jazz, three 30-minute screenings of rare 16-millimeter jazz films from the 1930s, including footage of Cab Calloway, Louis Armstrong, and Duke Ellington. All performances are free, but space at some venues is limited—seating is first-come, first-served. (A "Jazz Pass," available for a $125 donation, gets you preferred seating.) A free shuttle will transport attendees among the festival's various locations, with the Midway Plaisance acting as the hub. On Thu 9/22, the Museum of Science and Industry (57th and Lake Shore) hosts a $200-a-ticket cocktail gala with jazz singer Freddy Cole.
