I found another big-band old-style recording of the Mozart Requiem that I highly recommend. It is conducted by my favorite Dvorak conductor - Istvan Kertesz. Decca has been quietly re-issuing many of the Kertesz recordings that have been out of print for years on CD, or only available on old LPs.
This recording features the VPO and the Vienna State opera Chorus. I'm not familiar with the male solosits (Ugo Benelli, Tenor and Tugomir Franc, Bass), but they acquit themselves well. The women are Marilyn Horne and Elly Ameling. As much as I like Sylvia McNair in the Marriner recording, I think I like Ameling even more.
This recording definitely does not keep the chorus recessed at all. They are quite audible, and you can especially hear the men and the altos. The women sounded a tad old or middle-aged, but this may be due to the sound not being as soprano-dominated as it often is. Tempos are certainly slower than one would expect in HIP recordings, but often Kertesz timings on some pieces were quite close to Marriner's. The only spots I found a little overly slow were Rex tremendae and Confutatis. However, what they lack in speed they make up for in weight and majesty. Even though I'd prefer more drive in Confutatis, the piece is actually rather scary in this recording, probably due to the clear delineation of all the voices.
I think this would be a great choice for an old-school large-sounding reading of this work. Decca has released this on their Eloquence label with Mozart's Masonic music. The version I picked up was an old "London Weekend Classics" version (the series that had ugly cartoon covers) that only had the Requiem; so I cannot comment on the masonic music.
Speaking of Kertesz, some of the significant release from Decca/Eloquence include a Dvorak 2-fer that contains concert pieces that were often used as filler on the original LP issues. These include the following overtures: Carnival, Othello, In Nature's Realm, My Home, The Hussites; all of the Czech fairy-tale Concert overtures with the exception of The Wood Dove (which Kertesz didn't get to before his untimely death); Scherzo Capriccioso, and Symphonic Variations.
They've also released Kertesz' Brahms cycle which has always been highly rated along many other Kertesz recordings. Best get them now before they disappear again!
