Classical composer Wolfgang Amadeus Mozart was truly a musical genius, and some of his more than 600 compositions are considered the best of all time. Giants of the modern music world such as Daniel Barenboim, Sir Neville Marriner and Rene Pape pay tribute to Mozart by performing some of his masterworks. Included are Mozart's "Symphony No. 39," "Symphony No. 41," "Piano Concerto No. 9" and many more favorites.
