O Magnum Mysterium

The trademark qualities of a Robert Shaw-trained chorus included perfect tonal blend and balance, expressive phrasing, and superb tuning. As an interpreter, Shaw hewed to the middle road, steering clear of eccentricities and honoring the composer's intentions. On this tribute disc, we hear these virtues coalesce in works such as Poulenc's austere Christmas hymn "O magnum mysterium," one of three settings of the text here. Shaw was at his best in works whose fervent spirituality he shared, and the selection from Rachmaninov's Vespers, with its repeated alleluias, is a highlight, both radiant and passionate. But then, virtually everything here is a highlight: the Schubert part song done to a turn with soft singing projected in rounded tones; the curve of "Wondrous Love"'s melody perfectly traced; and "Amazing Grace" in Shaw's arrangement all the more moving for its calm dignity. The longest piece, Górecki's Marian hymn "Totus tuus," is otherworldly in an enthralled reading that never loses focus. Like all of Shaw's Telarc recordings, the sonics are first-class. --Dan Davis
