Oh I can post lots of Callas performances that I enjoy in spite of glaring technical faults, that I love. I'll start with an extreme version. Callas' rendering of the Eboli aria from Don Carlos, "O don fatale." I adore this one. It's rife with all sorts of unhealthy vocal tension, pushed voice, shrieking wobbly top, not well mixed low passaggio into raw chest, an overly dominant chest pushed too high, and a shaky hollowing middle register. Callas isn't even a mezzo and has no business attempting one of the most difficult and perhaps most dramatic of all arias in the entire mezzo repertoire. Well, in spite of all of that she manages to phrase better than anyone else who sings this aria IMHO. The phrases are arched perfectly into conveying the extremity of Eboli's emotions, and capture the fire and thunder of Verdi's pulsing impetus like nothing else I've heard, no matter how great the voices of many other great mezzos I have heard. The volcanic temperament of Eboli suits her perfectly, and she wears it like a glove. I adore Giulietta Simionato in this as the ultimate Verdi mezzo to my ear, but I have to admit that Callas phrases this aria better and I am obsessed with Callas' rendering of this. In my mind's ear I fantasize Simionato's voice being used by the mind of Callas and singing this.
