This production is not new. The MET back in spring 2006 had a first go at this, with roughly the same cast, but with some significant changes, too.
First of all, in the title role, the former bass baritone Simone Alaimo's starry performance that outshone both Norina and Ernesto is not there in this live recording. John del Carlo simply does not own the same degree of vocal clarity and verbal incisivness of Alaimo that is required of the title role.
Of course, too bad that here, in an important reprisal of this opera by the MET, they could no longer hire Juan Diego Florez to sing Ernesto. Last time round, at least in one performance, Florez did not finish the entire show owing to a slight ailment in the form of 'allergy', and the serenade "Com'e gentil" was tackled by his understudy Barry Banks, a very capable coloratura tenor in his own right.
Matthew Palenzani isn't bad as Ernesto; just that he lacked the quality to make the role really 'shine'.
As for Netrebko, I must say that she is a bit over the top in this production as Norina. She has to obtain an outfit that is at least two sizes bigger than the former 2006 suit.
The crux of the matter, however, is that her Norina isn't just sharp and witty - she is outright a shrew: spiteful, even a bit sluttish (considering the all too 'over' duet with Dr. Malatesta). Norina's love for the 'poor' Ernesto does not seem to exist as the opera progresses. Netrebko sang well enough, and would have been better heard than seen for the over the top acting, some thing so rare to find in the case of Netrebko.
Mariusz Kwiecien, like Netrebko, was in the 2006 MET production. Here is a stylish singer with a coloratura technique so secure and nature that is really hard to beat.
In short, the star of the show is Dr. Malatesta.
What do you think of that?
