Florence, 1299: the greedy relatives of Buoso Donati have gathered to learn who’s going to inherit the dead man’s estate. They’re all disappointed, though, when they realize that Buoso left everything important to a monastery. Enter Gianni Schicchi, an outsider with a harebrained scheme to rectify matters. Puccini’s comic opera first premiered in 1918, whereupon it was an immediate hit. Stonington’s Salt Marsh Opera Company has been performing in southeastern Connecticut since 2000, though occasionally they’re nice enough to cross the border into our opera-starved state. This is a fully-staged production with piano accompaniment.
