This occasionally off-the-wall but finely sung and colourfully staged La Cenerentola was Rome Opera’s first foray into the media market, shown on television and in cinemas across Italy in 2016. It clearly had the funding. Emma Dante’s production will not have come cheap – Vanessa Sannino’s costumes are a particular feature – nor would the singers, given that this is as good a Cenerentola cast as any international house might currently muster.
