When François Couperin published his Mass for the Convents in 1690, he had just turned 20, yet he had created the most exceptional collection of organ music to be written during the reign of Louis XIV. On the magnificent and historic Great Organ of the Royal Chapel of Versailles, over which Couperin presided from 1693 to 1730, the celebrated organist of Notre-Dame de Paris, Olivier Latry, performs a sumptuous version of this Organ Mass which, in a world premiere, is interlaced with captivating Chants sur le Livre, those sublime holy improvisations unique to French baroque music... for a moment of eternity.
