Pianist Rudolf Serkin is often recalled as one of the 20th century’s most commanding performers of Mozart, Beethoven and Brahms. But he was always a masterful Schubertian as well. After the war, he became American Columbia’s premier pianist in the Classic-Romantic repertoire. This 5-CD box gathers his recordings of the last two Schubert Sonatas – two different ones of the great B flat, D 960: one from 1975 and a live 1977 performance from Carnegie Hall – as well as the Impromptus, Moments musicaux, the “Trout” Quintet (from the Marlboro Festival with “an enthusiastic group that rises to the work’s challenges and Serkin’s inspired promptings” – AllMusic.com) & the exquisite late chamber songs “Auf dem Strom” and “Der Hirt auf dem Felsen”, in which he is joined by soprano Benita Valente, horn Myron Bloom and clarinet Harold Wright.
