This album features works by composers for whom the conception and creation of music was intimately bound up with a religious attitude towards the world. Before the birth of aesthetics in the 18th century, the symbolic or “external” meanings of music resided in the music itself; neither its expressiveness nor its purpose as an integral part of social and religious rituals were separated from a larger context of moral and spiritual considerations. In this sense, although their tonal languages and forms differ greatly, later composers such as Liszt, Franck and Messiaen followed the spirit of Bach, reflecting a musical philosophy in which musical means and theological ends were deeply intertwined, if not one and the same.
