Time Out says
Every September, the stars come out a Millennium Park to celebrate the beginning of opera season with a free outdoor performance. Attendees will get a preview of Lyric Opera's upcoming slate of shows, including from La bohème, Mozart’s Idomeneo and Verdi’s Il trovatore. The stars of the upcoming production of La bohème will be joined by the Chicago Children’s Chorus, members of the Ryan Opera Center as well as the Lyric Opera Orchestra and Chorus.
