“Blockbuster Weekend was how the City of Chicago billed its trifecta of free performances that included concerts by members of the Chicago Symphony Orchestra on Sunday afternoon and the Lyric Opera of Chicago on Saturday night. Each event attracted blockbuster crowds — some 10,000 for the CSO and 12,000 for the Lyric, according to a city spokeswoman. Now, all the symphony and opera have to do is translate that great wave of popular enthusiasm into paying customers, and nobody will be crying deficit.”
