Query: The only butterfly you'll ever need

I own four recordings of Madama Butterfly, each with its merits--the old classic with Gigli and Toti dal Monti, Bjoerling and de los Angeles, and Campora with Tabaldi. Then there is this one, in which the orchestra,the singers and the conductor are all on the same page. All of the singers are perfect for their respective roles--Bergonzi is subtle and insightful and even more so is Renata Scotto. There are other elements that bring this together in one of the "Great Recordings of the Century", to which I would add, of any century. In the final analysis, however, the deciding factor in the success of this great work of musical and recording art is Sir John Barbarolli. If you are a lover of Puccini and Madama Butterfly in particular, you should own more than one recording, if only to make comparisons to this one. Each will have its qualities, but none come close to the completeness of this one. Get it before it disappears as so many great ones do.
