The Library of Congress is sporting a strong spring concert season, despite ongoing repairs to its Coolidge Auditorium. On Feb. 21, the Washington Men’s Camerata will perform a program of Samuel Barber, Amy Beach, Irving Fine, Arthur Foote, Carl Maria von Weber and Richard Wagner drawn largely from the library’s collection of manuscripts. The library will present pianist and wit Stephen Hough at St. Mark’s Episcopal Church on March 21, playing a program including works by Liszt, Scriabin and one of his own partitas. But I’m most excited for the May 4 appearance of the Orpheus Chamber Orchestra, which will pay tribute to the legacy of conductor Andre Kostelanetz with a program of Mendelssohn, Mussorgsky and new work by Danny Elfman (commissioned by the library, the Los Angeles Chamber Orchestra and the National Symphony Orchestra of Ireland).
