Rising from the 1990s atmosphere of chant-mania came an idea from someone at Sony to compile a choral disc that would present the genre in an attractive, commercial package. This recording does a fair job of fulfilling that task. The program features some of the finest plainchant, chant-based works, and music written for the Holy Week liturgy, from composers such as Gesualdo, Monteverdi, Lotti, and Allegri. Of course, the famous Miserere by Allegri is here, with its starring high-treble solo--and the disc's liner notes give an unbelievably lengthy and rambling discussion of the work's history and various transformations, along with information about the liturgical significance of Tenebrae, the Miserere text, choral singing in Rome, and descriptions of the other pieces on the disc. The best bet here is just to listen to the music--it speaks very well for itself. --David Vernier
