Martha Argerich, whose appearances are all too rare, comes to the Proms with a leading American orchestra under its dynamic music director. Schumann's great piano concerto is the centrepiece of a programme which begins with Carl Ruggles's classic of the modern repertory and ends with Stravinsky's pagan ballet score.
