The Chicago Symphony Orchestra kicked off its 77th annual summer residency at Ravinia last week to rave reviews, with theSun-Times saying what looked strong on paper was even stronger in performance. The Chicago Tribune observed, “The verdant lawns were overflowing with members of the picnic-hamper-and-candelabra set. Metra trains rumbled through the park at the usual inopportune moments. Birds chirped in time with Beethoven. All, or nearly all, seemed right with the world.” The CSO residency continues through Aug. 16.
