Best known for unearthing long-buried treasures of the Bel Canto period, Teatro Nuovo gives New Yorkers their first taste of live, full-length opera since the lights went out in March 2020. “This is a moment for both continuity and novelty,” reads an announcement from the company, “so instead of our usual rarities, we decided to return with an opera known and loved by all, but to do it in our radical new way. Teatro Nuovo’s mission is about empowering the individual singers and players who create the core experience of opera.” Ergo, an orchestra of 35 players, same number as at the premiere in Rome in 1816. Ergo, no stage director or conductor— kingpins unknown in Rossini’s time. The proof, as ever, will be in the pudding. Critics have called earlier efforts by Teatro Nuovo transformative, revelatory. We can’t wait. Outdoors in Lincoln Center’s Damrosch Park, alongside the Metropolitan Opera. —M.G.
