Jean-Joseph Mouret (1682-1738) broke with operatic tradition with his ballet-opera Les Fêtes de Thalie, daring to include contemporary characters in the story rather than only historical or mythological ones. Opera Lafayette will present the modern premiere of this opera on May 4 in Washington, D.C., and on May 5 in New York. With music direction by acclaimed baroque specialist Christophe Rousset, the production will be crafted by Claire van Kampen, who has worked extensively at the Globe Theatre in London.
