The variety of different approaches to the Requiem is incredible - an endless source of fascination. Don't forget the "other masses"- Beethoven's Missa Solemnis is the equal of any in scale, majesty and power. If you like this kind of big choir, soloists and orchestra spectacular you probably shouldn't miss Mahler's Eighth symphony.
The Fauré, of course a much more subdued and contemplative affair. If you were to consult The Gramophone, they'd probably steer you towards a chamber-sized performance rather than the supposedly discredited orchestral version. However, I have a real soft spot for the Charles Dutoit recording on Decca with the Montreal Symphony and chorus with Kiri Te Kanawa and Sherrill Milnes (although I should probably revisit the Willocks HMV LP for the sake of contrast). The Dutoit is a beautiful, serene performance in spectacular sound.
