Not too many CDs of new opera recordings, at least of mainstream repertoire, come my way these days. Studio recordings have become rare and the usual medium is a video recording, itself a spin off from a live broadcast; TV, cinema or web, of a live performance. This makes sense to me. Just listening to an opera has always seemed a second best. Anyway, that’s all by way of saying that I was a bit surprised to find myself listening to a CD edition of a live recording of Puccini’s Manon Lescaut from the 2016 Salzburg Festival. How did this recording happen you ask? The answer is on the box, where Anna Netrebko in the title role, gets top billing, even over the composer.
