Conductor uncorks a Bolcom birthday toast, and pours dark, bracing Fifth of Tchaikovsky

Review: The rewards just keep coming at this summer’s Grant Park Music Festival. After a splendid opening stint of concerts, artistic director Carlos Kalmar gave place to conductor Dennis Russell Davies on July 6, and the result was yet another stellar program – this one offering an 80th birthday tribute to composer William Bolcom with his Fourth Symphony as well as a potently dramatic take on Tchaikovsky’s Fifth Symphony.
