Any opinions out there on Callas's version of Madama Butterfly within the EMI reissues? I can live with the remastered mono sound, especially if the disc is in the same category as Callas's Tosca, which at least one reviewer has called the greatest opera disc ever. I also have her Boheme, so I suppose I should spring for Butterfly just for symmetry's sake. Listers, what say you? Mitch Friedfeld
