Choral Music Suggestions

I would suggest you pick up the Hyperion SACD of works by Morten Lauridsen, with his Lux Aeterna and O Magnum Mysterium. A contemporary composer with his own musical language, but some of the most moving choral music I have ever heard or sung. You might also want to check out some of the recordings by the smaller English and other choirs such as the Cambridge Singers, The Sixteen, the Tallis Scholars, Chanticleer or the Corydon Singers, among others, they have made a number of recordings of some varied smaller scale choral works from all periods that might get you interested in the works of some of the composers of choral music. And if you want to venture into some larger scale choral works which still work for smaller choruses, there are a number of fine recordings of the Faure and Durufle Requiems that you could buy, two of my favorite works in the genre.

My favorite scaled down version of the Durufle Requiem (probably because I know some of the singers and have heard them perform in concert and at a few funerals) is the Voices of Ascension recording on Delos, surprisingly called The Durufle Album. If you can find it (long since out of print, as Delos sadly is no more, I believe), one of the things I like about it is that the women in the choir pretty much sing straight tone (little or no vibrato), which fits the piece beautifully, since it is based on plainsong chants.

The Herwigge discs mentioned by Newbee are excellent versions of the Faure.
