Vladimir Jurowski marks his return to Symphony Center with Shostakovich’s Symphony No. 8. In this immense wartime symphony, Shostakovich searches for hope and renewal beyond the anguish of violence and honors the ordinary people who contributed — and suffered — away from the frontlines. Celebrated pianist Martin Helmchen brings his “powerful yet refined approach” (The New York Times) to Mozart’s Piano Concerto No. 25. This late Mozart masterwork navigates a fascinating series of twists and turns — from its expansive first movement and tranquil second to its triumphant finale.
