Have no doubt about it, this is the greatest "Don" on disc. I've listened to many recordings, and this one absolutely eclipses them all. Fricsay, Davis, Krips, all nothing next to Giulini. Giulini's conducting is thrilling, the brilliant Philharmonia Orchestra (the best orchestra in England at the time) is pitch-perfect. And the singers are marvelous. Wachter's Giovanni is smooth and stylish of voice, and his defiance of Heaven in the final scene is rousing. Schwarzkopf's Elvira is beautiful and moving. Sutherland's Anna may not be the last word in rage, but the singing is glorious, and her Don Ottavio, Luigi Alva, sings gorgeously. He sings the long coluratura line in "Il mio tesoro" in one perfectly phrased breath. Taddei as Leporello is moving, musical, and quite funny. Sciutti and Cappuccilli's Zerlina and Massetto are sung, as is everything else, perfectly, and their characterization is, on the one hand, charming and sweet, and, on the other, more knowing and cunning than one might suspect. Frick's Commendatore/Statue is as powerful and dark as one could reasonably expect.
All in all, with a great conductor, a great orchestra, a great cast, and great sound, you can't live without this set.
