The London Symphony Orchestra has announced a cast change for “La Rondine.”

The orchestra said, “Nadine Sierra has had a recent medical procedure, the recovery from which is taking longer than anticipated. She has therefore had to withdraw from the LSO’s performances of ‘La Rondine’ on 10 and 12 December. The role of Magda will now be sung by Carolina López Moreno.”

Moreno has performed at the Puccini Festival Torre del Lago, Carnegie Hall, the Metropolitan Club, the Berliner Philharmonie, the Jugendstil-Festhalle Landau, and Cambridge University in England, among others. She has performed the works of Offenbach, Verdi, Mascagni, Leoncavallo, Mercadante, Poulenc, Puccini, and Nino Rota.

Moreno is set to join a cast that includes Serena Gamberoni, Michael Fabiano, Paul Appleby, and Ashley Riches. Sir Antonio Pappano conducts the London Symphony Orchestra.
