The music on this CD is not what most people consider "Gregorian Chant". The music presented here is taken from the "Old Roman" chant repertory (ca. 7th-8th Centuries) which pre-dates what is most referred to as Gregorian Chant. The Gregorian Chant which most people are familiar with actually comes from the Carolingian Empire (ca. 850-1000), which came into existence later than the Old Roman period. Hence, the reportoire from the Old Roman period is unsingable if sung in the style suggested by Gregorian scholars for Carolingian chants.

Conductus, organum, and discantus may not be words in your everyday vocabulary, but these terms identify musical forms that defined everyday musical activity during one of music history's most fruitful periods. The 12th century in France, especially in Paris–the artistic, educational, and religious center of Western Europe–saw enormous progress in the arts, architecture, and education. Not surprisingly, technical and theoretical aspects of music advanced as well. On this disc, the six-voice men's ensemble Lionheart demonstrates in vivid, rich vocal tones the sometimes stark but always powerful sound of Medieval chant and its expanded two- and three-part forms. The liner notes give clear explanations of the compositions and provide the listener with meaningful historical context. But listening to these excellent voices is not just an educational experience. The music has an inherent purity, sensuality, and honesty that's refreshing and reassuring.
