With Pierre Boulez's 2nd Piano Sonata Idil Biret not only makes her American recording debut, but also presents the first U.S. recording of this important contemporary work. Composed in 1948, this sonata occupies a position that exerted a causative influence upon Boulez's subsequent music. It's experimental and ground-breaking nature may be better understood if one regards it as having grown out of a response to Webern's Variations (1936), the companion piece on this album. The rigid, geometric patterns of Webern's work, the classical purity of it's encompassing organization, seems to have served as a base of departure for Boulez's broadened structures that are equally rigid but incomparably more complex. It is this very complexity that conceals the strict framework of the entire composition and projects it as the product of an ardent improvisatory impetus. It demands from it's interpreter a similar approach, along with technical prowess and intellectual control of the highest order. It was only a matter of course that this work, together with influences emanating from other sources (chiefly John Cage), should lead the path not only to open-form and aleatory compositions, including Boulez's own 3rd Piano Sonata, but also, through it's new pianistic language, urge the development of a whole new generation of virtuoso pianists. (Ilhan Mimaroglu, 1973)

Pierre Boulez's early ambitions to become a concert pianist provided the impetus to write piano music as a composition student at the Paris Conservatoire. The Theme et variations pour la main gauche and Trois Psalmodies reveal his extraordinary talent in their compelling mix of energy, drama and playfulness. Presenting these works alongside two later compositions provides a unique glimpse into the full arc of Boulez's musical journey. These pieces are powerful, their emotions raw and unfiltered, offering listeners a chance to experience the early foundations and mature reflections of a master composer.

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

Quatuor Diotima celebrates Pierre Boulez' centenary with a recording of his Livre pour quatuor, containing the world-premiere of the piece's fourth movement, which the composer conceived in close cooperation with the members of Diotima, and was completed by Philippe Manoury after his death. This recording adds a fascinating chapter to Boulez's "work in progress", and is a fitting successor to the quartet's acclaimed Ligeti recording from 2023. Quatuor Diotima is one of the most in-demand chamber ensembles in the world today, and has worked in close collaboration with several of the greatest composers of the late twentieth century. Reflected in the mirror of today's music, the quartet projects a new light onto the masterpieces of the 19th and 20th centuries. The quartet returns to PENTATONE after their acclaimed Metamorphosis Ligeti (2023) and Bruckner & Klose String Quartets (2024), which was awarded a Jahrespreis der Schallplattenkritik.
