Ludmila Berlinskaya has an impeccable pedigree. Daughter of Valentin Berlinsky, leader of the Borodin Quartet, she grew up in the company of some of the greatest Russian musicians of modern times, such as Richter (whose page-turner she was), Oistrakh, and Rostropovich. A fine chamber musician and an impressive soloist, she offers four major works for the piano by a quartet of great composers. Medtner’s sonata, which gives the album its title, is beautifully judged, while she invests the Schumann with real poetry, and charms with Ravel-playing of great flair.
