After years of frustration, Mozart enjoys great success on the operatic stage and a meteoric rise in the Viennese artistic scene. He essentially reinvents the keyboard concerto in the process. He also breaks free from his Salzburg employer and his family -- and he marries Constanze Weber. It's the third of five episodes on Mozart, kicking off our new podcast The Great Composers. The series, hosted by Karla Walker and Scott O'Neil, offers an intimate look at some of history's greatest musical minds. Subscribe so you don't miss an episode.
