Query: Very good album

At this bargain price, I found this CD surpringly good. The selections are from many first-rated albums from EMI. Most of them such as duets from "Le Nozze di Figaro", "Der Rosenkavalier" and "Madama Butterfly" are very good indeed. However, Gedda is the real star of this album. His duets from "The Pearl Fisher" and "Carmen" are among the best on recordings. The only complaint here is a duet from "Lucia di Lammemoor". The tempo is so funereal. Alfredo Krause sounds very aged and tired. Gruberova is not at her best. It could have been better with Callas and di Stefano.
