Performer: Emily Grace Righter

In recent seasons, the New York City Opera has largely limited itself to chamber operas. Its newest production marks a renewed ambition: Rossini’s Mosè in Egitto, a proto grand opera that ends with nothing less than the parting of the Red Sea.

Describing its new production of Francesco Cavalli’s 1668 opera Eliogabalo, the Gotham Chamber Opera compares the exploits of titular depraved Roman emperor Heliogabalus to Salome. There’s an obvious mistake here: Salome is an opera; Heliogabalus was a historical figure.
