The vocal ensemble Chicago a cappella kicks off its 25^th anniversary season at Pilgrim Congregational Church in Oak Park with a musical tribute to the city featuring Geoffrey Baer.

WTTW’s Emmy-winning host (10 that Changed America, A Weekend in Havana, Chicago’s Lakefront and many more) will serve as narrator for Chicago, Chicago -- a “Chicago time capsule” featuring the 10-voice ensemble. The program will include historic songs such as “Follow the Drinking Gourd,” a nostalgic “Chicago (That Toddlin’ Town),” and “Sweet Home Chicago.” The ensemble will use these melodies, vivid projections illustrating the city’s past and present, and Baer’s narration to delve into music from the Columbian Exposition (marking its 125^th anniversary), the Great Migration, the birth of blues and gospel, our beloved skyscrapers, champion sports teams, and more.
