It’s summertime in Chicago. You feel it along the lakefront, on the beaches, in the parks and streets, at the festivals. Itâ€™s music to the ear, outdoor concerts as backdrop to conversations in every language. Immigrants, tourists, performers, extended families and friends seizing the day and whiling away the nights. Here’s a cloudburst of festivals and events we visited last summer when we recorded the voices and stories of 150 people who help bring this city to life. Enjoy.
