ChicagoFest was a summer music festival in the city of Chicago, started in 1978 by Mayor Michael Bilandic. It was held annually at Navy Pier, and lasted for roughly two weeks. It featured sixteen separate stages, each sponsored by a national retail brand and a media sponsor compatible to the stage's format, e.g. Rock WLUP and The Chicago Tribune, Jazz and Miller Brewing Company, Blues and WXRT, that broadcast live from the festival.
