Anticipating Fat Tuesday, Mardi Gras, Carnival, or however you refer to the blowout before the beginning of Lent, the Akron Symphony joined forces with Neos Dance Theater on Friday, February 8 in E.J. Thomas Hall to produce its latest community extravaganza: a fully choreographed performance of the ballet score to Stravinksy’s Petrushka. Set during a Shrovetide fair, it’s a tragic tale acted out by puppets, but revelry was also in the air: at the end, the stage was filled with balloons that the cast were happy to share with the audience.
