The new scores were performed with much the same power and clarity that Orpheus brought to a pair of more familiar works. A suite from Bernstein’s “Trouble in Tahiti,” in a new arrangement by Paul Chihara, opened the program with an explosion of lyricism and rhythmic vitality. With the “Symphonic Dances From ‘West Side Story’ ” as a model, Mr. Chihara redistributed the opera’s vocal melodies to the strings and woodwinds, and had the brasses supply the jazz elements. The orchestra closed the concert with a beautifully sculptured performance of Copland’s durable “Appalachian Spring” Suite.
