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.

In 1997, Marcel Pérès and his Ensemble Organum began a simultaneous exploration of the Mozarabic rite (the liturgical chant peculiar to the Christians living in Spain at the time of Arab rule) and of the Samaa spiritual practice of Morocco. Setting aside the theological differences between the two faiths, the artists discovered a great deal of kinship between the two forms of musical expression. A veritable utopia, the idea for this recording then suggested itself: through music, to regain the lost accord of human brotherhood.

This recording came to fruition thanks to nearly 25 years of effort. In 1997, Marcel Pérès and his Ensemble Organum began a simultaneous exploration of the Mozarabic rite (the liturgical chant peculiar to the Christians living in Spain at the time of Arabrule) and of the Samaa spiritual practice of Morocco. Setting aside the theological differences between the two faiths, the artists discovered a great deal of kinship between the two forms of musical expression. A veritable utopia, the idea for this recording then suggested itself: to regain the lost accord of human brotherhood through music.
