"Every Tuesday in June, the MCA has free live jazz on their back terrace from 5:30-8:00pm. You can reserve seats online, or, if you want to make a picnic out of it, you can experience the music (and hopefully not too humid weather) on MCA’s lawn. Though outside snacks or alcoholic beverages aren’t allowed, they have a bar setup and a small rotating food menu. Tuesdays are also free museum days for Illinois residents, so you can have an afternoon of surrealist photography before an evening of Charles Mingus. Click here to see the line-up." - john ringor
