We went to a lunch time concert at St Andrew's Hall. Harpsichord and a small group of other instruments from Britten Sinfonia- the link is to the Cambridge and London concerts - but the line up and programme was the same.
It was an interesting concert - some of the pieces were "challenging" listening, and I suspect the performers found them challenging to play as well.
Afterwards, there was a little crowd around the harpsichord, which was specially made for Mahan Esfahani in Prague. It is driven to all his concerts - not a small undertaking.
