Acts slated for Pioneer Court were moved to the main stage near the Chicago River. Tickets now sell for $150 to view the attractions -- which include fireworks and performances by the band Chicago and alt-rockers American Authors -- along "Broadcast Boulevard" on Upper Wacker Drive between Michigan Avenue and Columbus Drive. Adults 21 and older can pay $99 to watch the event with a dinner buffet at the "Corona Beach House," a heated space at 225 E. North Water St.
