Pierre Boulez (French: [pjɛʁ bu.lɛːz]; born 26 March 1925) is a French composer, conductor, prolific writer, and pianist. He is also the founder and former director of the Paris based Institut de Recherche et Coordination Acoustique/Musique (IRCAM).
In his early career, Boulez played a key role in the development of integral serialism, controlled chance and electronic music. This, coupled with his highly polemical views on the evolution of music, gained him the image of an enfant terrible.
As a conductor, Boulez is known mainly for his performances of Béla Bartók, Alban Berg, Anton Bruckner, Claude Debussy, Gustav Mahler, Maurice Ravel, Arnold Schoenberg, Igor Stravinsky, Edgar Varèse, Richard Wagner, and Anton Webern. He has been awarded a total of 26 Grammy Awards during his career.
