So, as you may have noticed, the Met's Tosca casts through November 2 now look rather different. Out: Massimo Giordano and (crucially) excellent-singer-turned-bad-conductor Placido Domingo. In: Roberto Aronica and Paolo Carignani, the latter taking this on between runs of Turandot and Boheme. The four shows led by Carignani (the start of the revival tomorrow night has Marco Armiliato, who's been less than inspired in two shows already this month) include Angela Gheorghiu's two scheduled nights at the Met this season. Gheorghiu was absolutely inspired in her two Puccini nights last season, and though I suspect it won't be the same without Michael Fabiano (her tenor partner for those Bohemes), October 29 and November 2 are probably now deserve a hearing.
