Grayslake residents were treated to a Ravinia-style concert Tuesday night in Centennial Park.
The Mike Flack Octet performed some cool jazz as people sat in their lawn chairs and opened up their picnic baskets.
Flack is a professor of music at the College of Lake County where he teaches music theory and history as well as conducting the school's jazz combo, wind ensemble and jazz ensemble.
Flack also leads several popular professional ensembles in the Chicago area, including his jazz orchestra, quintet and trio.
