Those familiar with the works of St. Olaf's know that the choir is part of a long tradition of Scandinavian chorale singing, which often features the compositions and arrangements of the venerated F. Melius Christiansen. One of his arrangements, "O Day Full of Grace," is included here, as well as a seventeenth century spiritual, "O Savior, Throw the Heavens Wide"; a Greek vespers (evening prayer service) hymn, "Hail, Gladdening Light," and various other liturgies. There is piano accompaniment on "Gloria in excelsis Deo" and the spiritual, "Here's a Pretty Little Baby." The purity of the tones and blend is all the more amazing, as the recording was done live. Elegant and pristine.
