On October 6, 1927, the American public watched in amazement at the first world projection of a sound film, The Jazz Singer, a production composed of several sung scenes. A formula whose French production hastily seized, coupling popular tunes to the film narrative. The result was an artistic bond that gave birth to many masterpieces of the song and the big screen, coupled with a long tradition of singers-actors, including Baker, Chevalier, Trenet, Piaf, Montand, Bardot and many others, whose voices are inevitably associated with the rich hours of French cinema.
