A reader emailed some days ago to ask if I had information on Rachele Gilmore, who made her unscheduled Met debut substituting for Kathleen Kim (Olympia) in the pre- and post-Christmas performances of Hoffmann. I've no personal experience, but YouTube does tell the tale:
Kim has recovered, but last night found illness knocking out the most important part of the cast: tenor David Pomeroy (who'd actually sung most of the dress rehearsal) made his official Met debut as Hoffmann himself in place of star Joseph Calleja. Pomeroy seems to have done OK, but let's hope Calleja is better by Saturday's final performance.
Meanwhile, as you may have heard, tenor Roberto Alagna -- also ill -- failed to get through Monday night's dress rehearsal of Carmen and merely acted the latter part of the show. Whether he'll recover to sing in tomorrow's production premiere/New Year's Eve gala (the cynical might think this the least bloodthirsty audience the house could arrange for a risky production) -- well, who knows? It's that time of year.
