Query: A fine introduction to a renowned operatic pairing!

Choose this reasonably-priced CD as a gift for a friend, or even to yourself. It provides a fine introduction to the renowned and near magical operatic duo of Maria Callas and Giuseppe di Stefano. There is a rare electricity here, their voices blended well, and they sang with tremendous conviction together. The "Puritani" excerpt is perhaps the weakest but still shows them in fairly good stead. And the Tosca? The lengthy excerpt (most of the last act) of their 1953 classic is generous by any standards. The Miserere from Trovatore, while a short excerpt only, is precisely etched and haunting. The Manon is propulsive and the Boheme is charming. Have friends who THINK that they wouldn't like opera? I've dazzled a good dozen by showering them with this invaluable "little" purchase---one of the rare real bargains in this lifetime. This was one of my first opera purchases, and I haven't stopped since.
