I think it's sad that an opera should be viewed as a star vehicle which ceases to exist the moment its star cancels
Was it supposed to be a concert performance or a staged production?
Entirely agreed - whatever happened to "the show must go on"?? I believe it was to have been a fully staged production, that went on to tour around USA and Europe.
Fleming's a singer who has never impressed me, and I fail to understand what the fuss is about. If her acting were better her voice might be suited to operetta or soubrette roles. Norma she is not, and never will be, and whoever cast her in this role was severely mistaken.
Sadly the reality of this escapade is that projects of this kind depend on the soprano's bankability, and without a name that would reel in the corporate sponsors and media flea-circus, the project is doomed to failure. There are a hundred sopranos who could easily sing Norma magnificently... but operas these days are cast on the basis of press-pics from ten years ago, and not on the basis of whether the performer could ever sing the role, or has even sung any similar roles
The fact they haven't even bothered
trying to secure an alternative performer speaks volumes about the facile level with which this project has been (mis-)managed.
