Watch BBC Proms online: Episode 49 Brahms – Piano Concerto No. 2 & Symphony No. 4

The Chamber Orchestra of Europe's second pairing of Brahms masterworks opens with a work long central to Emanuel Ax's repertoire which he has recorded with tonight's conductor. Brahms's Second Piano Concerto is even bigger in scale than the First and just as technically demanding. After the interval, the composer's astonishing final symphony, where the balance between expressiveness and iron structural control is most perfectly maintained. It ends with an imposing set of variations, Brahms's late-Romantic take on the Baroque-style passacaglia, which uses material borrowed from J. S. Bach.
