It's a big weekend at Blossom Music Center, the summer home of the Cleveland Orchestra: Bernstein's Symphonic Suite from On the Waterfront, Gershwin's Rhapsody in Blue, Stravinsky's Suite from the Firebird and Tchaikovsky's 1812 Overture — and fireworks! — are all on tonight's program that finds the orchestra performing under the direction of conductor Roderick Dox. The concert begins at 8 tonight at Blossom and repeats at 8 tomorrow night. Consult the orchestra website for ticket prices. (Niesel)
