It's common to talk about the 1953 de Sabata recording at the expense of this one. I would not do without either. This one has several advantages: 1) Though Callas's voice has deteriorated, she is in her skinny Callas voice here, not the fat Callas voice (where she sounds like she's singing into a bottle.) I like both, but if you prefer thin Callas, this is the Tosca for you; 2) This is a more histrionic TOSCA -- that doesn't make it better or worse, but it's definitely different enough to set it apart; 3) Her Vissi D'arte is her best, ever, and she recorded it many times; 4) The stereo sound is gorgeous; 5) I prefer De Stefano, but Bergonzi brings something special to this, too; 6) Gobbi, in the spirit of this production, pulls out the dramatic stops. This is the melodramatic TOSCA, and the '53 is the dramatic TOSCA. Two versions, both great.
