Swedish trumpeter Håkan Hardenberger, a longtime collaborator of Andris Nelsons, returns to Symphony Hall as soloist in a concerto composed for him, the Viennese composer HK Gruber's Aerial. Featuring piccolo trumpet and cow's horn as well as standard trumpet, the concerto makes full use of Hardenberger's considerable virtuosity and expressive range. Mahler composed his Fifth Symphony in 1901-02. His first completely instrumental symphony since No. 1, it marked a new, highly individual, and influential approach to writing for orchestra that would carry through the remainder of Mahler's symphonies. The Fifth includes the famous and moving Adagietto movement for strings and harp.
