The pianist-conductor Jean-François Heisser shows here his exceptional rapport with the musicians of the Orchestre de Chambre Nouvelle-Aquitaine (the former Orchestre Poitou-Charentes), a formation with a reputation for commitment and high standards. Their vision of the five concertos of Beethoven, directed from the piano for the first time in a recording made in France, abolishes the frontiers between chamber and symphonic music.
