Rachmaninoff: Vespers (Mass for Unaccompanied Chorus)
If those Gregorian chant discs seem a little, well, limited lately, perhaps it's time to move on to something equally spiritual but a bit more harmonically interesting. This disc, well-performed by the Robert Shaw Festival Singers, and conducted by the legendary choral leader, features a ravishing score by Rachmaninoff and is sung a capella, as is all Orthodox church music. (For a heartrendingly beautiful number, listen to the second cut, "Blagoslovi, Dushe Moya," or "Bless the Lord, O My Soul.") Along with well-tuned choral singing, there is a fine solo contribution by tenor Karl Dent.--Sarah Bryan Miller
