Although there are so many Don Giovannis available, this one is particularly interesting because of Taddei's interpretation of the title role, and, I rank him among the best. We know Taddei as an excellent Leporello. Here, he plays and sings an elegant seducer. In this sense he is closer to Thomas Allen than to Waechter or his co-patriots Siepi or Pinza.
Also the Leporello of Italo Tajo is vocally and dramatically very convincing, and the scenes where Taddei and Tajo play together are very enjoyable. Valetti's Ottavio is a strong argument for this recording as well, whereas the female cast is, similar to the recordings of the last decades, less convincing. Carla Gavazzi must have been a good Elvira, but probably this was recorded too late for her, Curtis-Verna is a reliable Anna.
Rudolf's conducting is - in a positive sense - unspectacular.
The remastered sound (still Mono) is the best I ever heard in a Cetra recording of that period.
