Music of the Baroque (MOB), in association with the Department of Cultural Affairs and Special Events, opens its 51st Season with its second “Baroque in the Park” open-air performance at the Jay Pritzker Pavilion (201 E. Randolph St.) on Friday, Sept. 10 at 6:30 p.m. The concert will be conducted by Music of the Baroque Music Director Dame Jane Glover. The program for “Baroque in the Park” features the world premiere of MOB’s first commission, “Spectacle of Light.” Composed by internationally acclaimed composer Stacy Garrop in honor of MOB’s 50th anniversary, the work’s debut was postponed due to the pandemic. Garrop found her inspiration for the work in an etching displayed on MOB’s website of a 1749 fireworks spectacle on the River Thames in honor of Great Britain’s King George II. Pavilion and lawn seating is free. For more information, including COVID-19 protocols, call 312.551.1414 or visit baroque.org.
