My husband took the elder children to hear Daniel Barenboim conduct the West-Eastern Divan orchestra in a programme of Boulez (Mémoriale and Messagesquisse) and Beethoven (Fifth and Sixth Symphonies). They got a slip in their programme saying that the interval would be after the second Boulez piece, not the first, but many people were unaware of this change and after the first Boulez made a dash for the bar/toilets/ice-cream stall/natter in the corridor with friends, and then missed the second. (It says something about the Proms audience that most of those so excluded tried to get back in to hear the Boulez).
I’m told that the orchestra sounded good, though some sections of it are more accomplished than others.
Some reviews:
