Marking his first season as its chief conductor, Sir Simon Rattle leads the Symphonieorchester des Bayerischen Rundfunks (Bavarian Radio Symphony Orchestra) in Mahler’s mighty Sixth Symphony. Sir Simon has been celebrated for his “complete command” (The New York Times) of this piece, one of the composer’s darkest and most impassioned symphonies. Its vast panorama includes cowbells to evoke the Austrian countryside and fateful hammer blows in its final movement.
