Classical music supporters and latent jitterbug-fl appers alike, take note: On Sunday, Sept. 30, at 5 p.m., the Bloomington DoubleTree Hotel and Conference Center will provide the setting for “The Great Gatsby Gala, A Roaring Fundraiser for the Illinois Symphony Orchestra,” your best chance to help fund the ISO while emulating F. Scott Fitzgerald’s glamorous prohibition-era hepcats and kittens. The night will include a special vocal performance by soprano Sarah Lawrence and tenor Calland Metts as well as dancing to the jazz stylings of Glenn Wilson and Friends. 1920s attire is encouraged.
