This chapter surveys Pierre Boulez’s recording career. It began in the 1950s, as a pianist in Mussorgsky and Stravinsky songs and directing incidental music by Milhaud. In the early 1960s, he conducted Mozart (with Yvonne Loriod) and C. P. E. Bach (with Jean-Pierre Rampal). His earliest recording of Le Marteau sans maître was made in 1956 and he first recorded The Rite of Spring in 1963. From the mid 1960s onwards, he recorded for Columbia (now Sony), including much of what is considered his key repertoire: Stravinsky, Varèse and Bartók; Debussy, Ravel and Messiaen; Berg, Schoenberg and Webern; and Boulez himself. In the 1980s, he made the first recording of the three-act Lulu and several new recordings of his own works. In the 1990s, for Deutsche Grammophon he made new versions of many pieces previously recorded for Columbia, as well as a Mahler cycle and, more surprisingly, works by Szymanowski, Richard Strauss and Bruckner.
