For pianist Yuja Wang’s newest album on DG, she wows with two perennial hits: Ravel’s Piano Concerto in G major and The Piano Concerto for the Left Hand in D major. Ravel composed both concertos between 1929 and 1930 and the latter was commissioned by the Austrian pianist Paul Wittgenstein, who lost his right arm during World War I. The young, stellar conductor Lionel Bringuier and Tonhalle-Orchester Zürich are the perfect partners.
