I just came across this video of the second act sextet from Rossini’s Cenerentola. It’s from a 1981 movie of the opera directed by Jean-Pierre Ponnelle. The singers are Francisco Araiza, Claudio Desderi, Paolo Montarsolo, Margherita Guglielmi, Laura Zannini, and Frederica von Stade. Claudio Abbado conducts. It’s a gem both musically and visually.
