Widely considered as one of the twentieth century’s greatest interpreters of Beethoven—and the first pianist to record that composer’s complete cycle of sonatas—Artur Schnabel is the subject of the latest release from RCA Red Seal Records (a division of Sony Classical). Bringing together all of his sessions for RCA Victor (recorded between June 16 and July 24, 1942), the two-disc set features Schnabel performing Beethoven’s Fourth and Fifth piano concertos—with the Chicago Symphony Orchestra under second music director Frederick Stock—and two of the final piano sonatas (nos. 30 in E major and 32 in C minor), along with Schubert’s Four Impromptus, D. 899.
