Fifty-five years after the release of their first recording, Katia and Marielle Labèque celebrate an extraordinary artistic journey with this new triple album, bringing together new recordings and archive selections spanning more than half a century. The Labèque sisters have consistently crossed boundaries between classical, contemporary, jazz, minimalism, and popular traditions. Commissioning works from composers such as Philip Glass and Bryce Dessner, performing on stages worldwide — from Mozart to minimalist composers — their openness has never wavered, and they have successfully combined artistic rigor with popular acclaim. On 55, Katia and Marielle Labèque demonstrate their enduring curiosity, their commitment to creation, and their unique role as bridges between eras, aesthetics, and musical worlds. With women composers not featured prominently enough in their back catalogue, 13 of the 25 new tracks are composed by 10 different women.
