This was the best Requiem of its time with the greatest solo quartet of its time. Today to our ears, it sounds dated. That's why I gave it four stars instead of five. This recording has flaws, but they are flaws of grandeur! Caniglia was one the greatest italian sopranos, but the voice turned squally in the top. We know that! But she is a always extremely musical and strong in the middle voice. Gigli was the successor to Caruso. He had one of the most beautiful voices in history with a dynamic range capable of huge fortissimi down to the smallest mezzovoce pianissimo.BUT, he also had mannerisms that would not be accepted today. Stignani is always a rock of strength, singing in tune and on pitch. No one has ever sung the bass part better than Pinza. The dating shows in the chorus parts, where that extremely full climaxes tend to crumble, but remember, Serafin was a brave conductor. He was recording huge pieces like Aida and the Requiem in the Rome opera house, before WWII. The technology of the day simply did not permit a real reproduction of what he and the chorus were doing. Another interesting fact is that this was recorded on 1939, on the eve of WWII. All in all, to me, this is a great recording, with great voices, all of which far exceed the limitations of the technology. I would not be without this recording!
