En reaction aux resonnances neo-classiques qui dominaient le paysage musical francais de l'apres Seconde Guerre mondiale, quelques compositeurs - emboitant le pas au groupe Jeune France (Messiaen, Jolivet...) - ambitionnerent de mettre en lumiere les grandes figures de la tradition moderne, Webern, Schoenberg, Stravinsky, Berio et quelques autres. Pierre Boulez fut sans aucun doute le plus celebre representant de cette nouvelle orientation. Compositeur mondialement reconnu, pedagogue, initiateur et directeur de nombreuses institutions (Ircam), il fut egalement l'un des plus respectes meneurs d'orchestre, mettant sa baguette au service du repertoire de son temps. Christophe LOINTIER & Patrick FReMEAUX. In reaction to the neoclassical resonances that dominated the French musical landscape post-World War II, a few composers - following in the footsteps of the 'Jeune France' movement that included Messiaen and Jolivet - made efforts to throw light on the great figures of the modern tradition, namely Webern, Schoenberg, Stravinsky, Berio and a few others. Pierre Boulez was no doubt the most famous of this new orientation's representatives, a world-renowned composer and teacher who initiated and directed numerous institutions such as the Ircam for example. He was also one of the most respected conductors to wield a baton over the repertoire of his day. Christophe LOINTIER & Patrick FReMEAUX
