Get discounted tickets to the August 31, 7:30 performance of Cheap Trick at the Ravinia Pavillion.  Still going strong after nearly 40 years, the Rockford, Ill.-based Cheap Trick continues to rock with the best of them, and the group is bringing its high-energy tour to the Ravinia Pavilion. In this performance, the group will be playing in full two of their biggest hits — 1979’s Cheap Trick at Budokan and 2009’s Sgt. Pepper Live — with a full orchestra. Cheap Trick was ranked No. 25 in VH1’s 100 Greatest Artists of Hard Rock, so you know the group will bring the noise. It may not be Cheap Trick Day in Illinois (that’s April 1), but the group will make the most of its homecoming at this concert.
