The very precious final opera of the Season is Mozart’s Così fan tutte, directed by Robert Carsen and featuring the La Scala debut of Alexander Soddy, a British conductor much in demand at Covent Garden, the Metropolitan, and the Staatsopern of Vienna and Berlin in a repertoire that ranges from Wagner and Strauss to Mozart and Italian opera. The melancholic geometries of affection designed by Mozart, which are less frequently performed at La Scala than the other titles in the DaPontian trilogy, nevertheless include the legendary version by Guido Cantelli at the Piccola Scala in 1956, the majolicaarrayed stage sets of Michael Hampe and Mauro Pagano reprised more than once by Riccardo Muti starting in 1983, and the pensive work by Claus Guth conducted by Daniel Barenboim in 2014.
