BSO Conductor Emeritus Bernard Haitink leads the final series of the 2017-18 season, an all-Brahms program featuring beloved pianist Emanuel Ax in the composer's monumental Piano Concerto No. 2. The turbulent First, the Second Concerto is a magisterial, far-ranging work of symphonic proportions, in four movements rather than a typical concerto's three. Brahms's Symphony No. 2 was composed relatively quickly in 1877, following his extended, years-long effort to complete the long-awaited First. The lilting Second Symphony is generally regarded as the most genial and relaxed of Brahms's four great works in the genre.
