The show starring jam band Dispatch, with guest Guster, instead will go on at the UIC Pavilion with the same 7 p.m. start time. Previously purchased tickets will be honored, and new ones are on sale now at TicketMaster.com.
A statement from concert promoter Live Nation said weather knocked the Charter One Pavilion's expansion project off schedule. The Northerly Island venue is being overhauled to boost capacity from 7,500 to 30,000.
Dispatch is scheduled to appear at a pre-show tailgate from 4:30 to 6 p.m. Saturday at the UIC Pavilion's Parking Lot 11.
Fans who bought $41 Charter One tickets will receive a $4 credit on their credit cards to refund a prepaid parking fee.
