Some nights you want to jump and jive to your old favorite party songs like YMCA and Stayin’ Alive. Other nights, however, you want to just sit and take in the exhilarating feeling of beautiful orchestral music. Plan on the latter sort of relaxation on Thursday, July 26th, as the Barton Rogers Big Band will be performing at the MacAlister Amphitheater in Garfield Park. The sounds of trumpets, woodwinds, and percussion will wash over you in a perfect symphony of sound. It will be the perfect ending to a picnic dinner in the park, and you won’t have to worry about remembering those moves and words. Or your wallet, because this pops is free.
