The Metropolitan Opera’s “Tosca” has been completely altered since its cast was announced earlier this year.

When the Met made its announcement earlier this Spring, Jonas Kaufmann and Kristine Opolais were the lead roles. Now the cast will be headlined by Vittorio Grigolo and Sonya Yoncheva.

Yoncheva, who was already scheduled to sing “Le Nozze di Figaro,” will be replaced by Ailyn Pérez as the Countess. This will be the Bulgarian soprano’s role debut. The same goes for Grigolo. The first performance of this run will be on New Year’s Eve and will be presented Live in HD.

Now Yoncheva, the seeming superstar of the Met, will be featured as part of the Live in HD series a whopping three times this season, a Met record for any major superstar in a lead role. In addition to “Tosca,” she will appear in “La Bohème” and “Luisa Miller.” Her performance in the title role “Luisa Miller” is also a role debut.

Opolais is said to have canceled for “personal reasons” and it is yet unknown whether her husband Andris Nelsons, who was scheduled to conduct, will remain in the pit for the run.
