Enjoy a free performance of Twelfth Night at Garfield Park Conservatory, 300 N. Central Ave., on Sunday, July 24th at 3p.m. Grab a blanket or lawn chair, pack a picnic and attend as you are. This week, the largest citywide event of Shakespeare 400 Chicago is coming to Humboldt Park and is free for all. Families and neighbors of all ages will enjoy the 75-minute abridged production of Shakespeare’s jubilant, music-infused romantic comedy, set against the backdrop of Chicago. Returning from last summer is Jazzology, who will perform to kick off the show.
