Rachmaninov’s First Symphony begins with a snarl, and gets angrier. A menacing skirl from the woodwinds, a triple-fortissimo blast from the brass, and then the full weight of the strings, hammering out one of those doomy Russian motto-melodies like lead boots dragging you to the bottom of the Neva. ‘Vengeance is mine; I shall repay’ glowers the epigraph that Rachmaninov inscribed at the top of the score, and you’d better believe it.
