Goodness knows where some of these recordings were found but it's true to say that they are real Golden Oldies, Mario Lanza, Maria Callas, Joan Hammond and the 'best pairing ever' for the Pearl Fisher's Duet of Jussi Bjorling and Robert Merrill (every recording since, and there are many, pales into insignificance,). It contains something for everyone - arias we all know and love and in some cases, even sing along with, it's irresistable. Even if one is not an opera buff - some operas are truly boring - this collection has all the best bits. The reproduction is good, we don't have a fantastic sound system but the sitting room is full of well-balanced sound and the Bose system in my car makes it sound even better.
