First up on Claudio Abbado's Royal Festival Hall date with the Orchestra Mozart: Haydn's Surprise Symphony.
And second: a surprise pianist.
Substituting for the previously-advertised Maria Joao Pires on 1 October is the elusive Martha Argerich.
Mozart's Piano Concerto No.9 in E flat is currently on the bill, but I wouldn't be surprised to see that change.
Still plenty of tickets left, but mostly at the back.
