This excellent disc of plainchant was given top ratings by NPR's Ted Libby. The ensemble is composed of superb professionals selected for their fine voices and musicality and is conducted by an early music specialist known for his many notable recordings. Performances are all very warmly attractive with clear, bright intonation and exact enunciation. The meaning and mood of each selection seems to be perfectly balanced between the word and the sound, and the effect is not only a spiritual experience, but an aesthetic one, as well. Prospective listeners shouldn't hesitate here based on ideas of cold, "monkish" sounds which only a few initiates could appreciate. Konrad Ruhland and his singers reveal great treasures in this "plain," supposedly simple music which brings thoughts of later great musicians such as Palestrina, Monteverdi, Bach, and even Brahms and others whose musical influences can be traced back to this source, this heavenly and earthly origin. Sony provides excellent notes and translations as well as warm and clear recorded sound. A classic which should remain in the catalogue.
