This Tosca, made in 1953 with the forces of La Scala, is a landmark in recording history.Conducted with searing intensity by Victor de Sabata, it teams Callas with two of her closest colleagues, the tenor Giuseppe di Stefano and the baritone Tito Gobbi - a performer who could rival Callas in dramatic finesse and power. Tosca's aria 'Vissi d'arte' (I lived for art) has come to be seen as Callas's personal manifesto.
