On June 5-8, Baltimore Symphony music director Jonathon Heyward will lead the orchestra in the world premiere of James Lee III’s Concerto for Orchestra. This is one of a series of concerts and educational programs focusing on the works of Lee, who is a native of Baltimore. Yefim Bronfman takes the stage for Beethoven’s Piano Concerto No. 5, Emperor; the program concludes with Smetana’s “The Moldau,” one of the six symphonic poems the Czech composer wrote about his homeland.
