Donizetti’s Anna Bolena, in a production by Stephen Lawless, opened last night at the COC. Bel canto fans, canary fanciers and, just maybe, the rest of us should rush and see it. The singing is extraordinary. The cast is led by Sondra Radvanovsky in the title role and she gives, pretty much, a masterclass in bel canto technique. The control is extraordinary with gleaming top notes, exquisitely floated pianissimo, genuine trills and real emotion. Only a slight raspiness occasionally evident in the recits even hinted that this was a singer who was too sick to perform only a few days ago. Where to go next among some very fine performances? Bruce Sledge as Percy I think. This was thrilling tenor singing with passion, ringing high notes and wonderful musicality.
