The other review is nonsense. This is the most devastating account of Butterfly on disc. De los Angeles said this was one of her favourite roles, and is shows. Unlike Callas or many other singers, there is no attempt to sound coy or twee when playing a 15 year old in Act 1. De los Angeles is wonderfully natural throughout. Of course, that can only be achieved by art of the highest order, and a good technique. Her attention to words, her subtle phrasing and her understanding of the role are unmatched, and she proves herself a surprisingly convincing singing actress. The highest notes take her to her limit, but no more so than Callas or Scotto, and those extremes suit the dramatic situation. If you just want a beautiful sound, without drama, then this may not be for you. But if you want a performance that will, as Puccini intended, break your heart, this is a great bargain.
With di Stefano and Gobbi, the supporting cast is ideal. Vivdly conducted and performed with passion, this is a classic recording. But the sound is definitely historic mono and a little shrill. Unfortunately this is the sort of sound that does not transfer to CD especially well. I have the original LPs - they sound far more mellow. But a few adjustments of treble tone on your CD player should mitigate the problem. And this is such a cherishable, embraceable butterfly that it's worth it.
