Casadesus inherited his musical talents from his father, Henri Casadesus, a personal friend of Saint-Saens with whom he organized numerous concerts. A former student of Pierre Dervaux and Pierre Boulez, Casadesus studied percussion, composing and orchestrating at Paris Conservatoire. Although he initially planned to work as a composer of film and theater scores, he veered towards a career as a conductor when he joined with Dervaux to form Orchestre Philharmonique Des Pays De La Loire in 1971. Since assuming leadership of Orchestre Nationale De Lille, Casadesus has maintained an amazing busy schedule. In addition to his work with the orchestra, he's conducted orchestras in Moscow, Prague, London, Dresden, and Leipzig and served as musical director for operas at the Paris Opera House and the Opera Comique.
