The concerts of this ensemble are always inspiring. The playing of these gifted musicians more than makes up in excitement energy what it may lack in finesse. The orchestra's ambitious season-ending concert at Carnegie Hall, conducted by its dynamic music director, Joshua Gersen, opens with Bernstein's "Candide" Overture, followed by the premiere of Conrad Winslow's "All Decays." (The Winslow piece is the latest in the orchestra's important First Music commissioning venture, which presents the premiere of a work by a young composer on every program.) The violinist Benjamin Beilman is the soloist in Barber's Violin Concerto. The program ends with Copland's exhilarating Third Symphony.
