Il s'agit manifestement d'une répétition (? ) on ne peut donc juger pleinement d'un point de vue vocal, mais effectivement l'ensemble est approximatif.
Not an aria for her. Tempo is much too slow to my taste. No vocal fireworks. No easiness in the coloratura. No sparkling ornamentation. There are other Cleopatra’s arias where she is wonderful, especially Se Pietà where she is sublime, but Da Tempeste is an aria she should have cut when she was singing the role on stage. Just my opinion, and M. Caballe remains one of my favorite singers ❤
