This composer dedicated a piece to Leo Schuster which he composed on vacation in Italy. One work by this composer of In the South had such a disastrous premiere due to lack of rehearsal time that it went unnoticed until Jacqueline du Pre resurrected it with a recording after the composer's death. That work was his Cello Concerto in E Minor. This composer argued that one of his works has a secret theme which "is not played." That work is dedicated to "my friends pictured within" and includes a movement entitled "Nimrod." For 10 points, name this English composer of the Enigma Variations and a work played at graduation
