I was there on Friday night and can report it was being recorded, presumably for Radio 3, although there was nothing mentioned in the programme. Radio 3's Opera on 3 page has it listed for broadcast on the 22nd of November which, being a Saturday, seems more likely than the Guardian's stab at the 3rd!
Juan Diego Florez in stunning form, btw, as was Aleksandra Kurzak as Matilde.
A typically waspish review from Edward Seckerson in the
Independent, whilst Richard Morrison's review in
The Times is spot on, especially about Florez's excellent comic acting: "
Think of Alan Rickman as the Sheriff of Nottingham and you’ll have some idea of how Flórez plays the grumpy, misogynistic and ever-so-slightly blood-crazed nobleman Corradino"!
