Quatuor Diotima celebrates Pierre Boulez' centenary with a recording of his Livre pour quat uor, 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 Liget i (2023) and Bruckner & Klose St ring Quart et s (2024), which was awarded a Jahrespreis der Schallplat.
