The terrace of the Museum of Contemporary Art in Chicago comes alive every summer Tuesday with an overflowing farmers market in the morning and free jazz concerts in the evening. Shop the market from 7 am to 3 pm to fill up on fresh fruit and vegetables; return at 5:30 for performances from some of Chicago’s quintessential jazz musicians. In between you can catch the museum’s Unbound exhibition, highlighting contemporary art after Frida Kahlo.
