Information for BBC National Orchestra of Wales at The Riverfront, Newport (Concert). Join us for a celebration of American classical music with our LA born Principal Conductor, Ryan Bancroft this May! Popular the world over, Barber's Adagio for Strings is one of the most recognizable pieces in the orchestral repertoire and probably his best known work – used in film and television, and poignant for its performance at Roosevelt's funeral and following the assassination of JFK, you're sure to have heard this iconic piece!
