Big news! Well, maybe we should just call it Bolshoi (Big) news. At a Mann Center preview party for the Aug. 2 and Aug. 3 performances of the Bolshoi Ballet, some dance aficionados stepped up to talk of their admiration for the dancers and anticipation of their appearances. Gathered for the party at the Bryn Mawr digs of Donald E. Callaghan (from left) are Mann board members Selma Glanzberg Krestal and Goncer Krestal, and Marciarose Shestack, with ballerina Olivia DePaulis of the Rock School, and the board's Samuel and Selma Savitz.
