Firstly let me thank The Wolf for his review, and say that I agree with it wholeheartedly. I would like to add a proviso, though, and that is to suggest that it is necessary to make some small allowance for the age of the original recording. I well remember buying the LP boxed set and being delighted by Decca's sound, at the forefront of fidelity at the time. This new version includes a Blu-ray audio transfer that is, at least in theory, an improvement over standard CD quality, and tempted me to purchase the newest incarnation of a historic (and arguably unmatched) performance. The Blu-ray disc is in stereo only, and it took careful listening on my part to convince myself that I could hear any improvement over the CDs. As with other older recordings that I have purchased, re-mastered into the best of today's formats, I was just a little disappointed. In this case I felt that treble was a bit restricted and clarity could have been better.
There are those like myself who will always want this recording on their shelves, and rightly so. As for me, the music is the most important aspect, and I find that I prefer to listen to (and watch) Andris Nelsons conducting a 50th anniversary performance from Coventry cathedral, with excellent pictures and sound (see the reviews on Amazon UK, to which I wish to add little except to add the one small critical comment that the children's choir could have been placed in the rear speakers to match their position on camera, behind the audience). Value is always in the eye of the beholder, but I feel this issue offers more for the outlay than the remastered Decca.
I beg all who wish to own this great recording, conducted by the composer, not to hesitate. However, if you are simply looking for a fine AV recording of the marvellous War Requiem with no preconceptions, give Nelsons' Blu-ray a try.
