Cultivated at the height of the French baroque, Henry Du Mont's Grands Motets were written for the court of Louis XIV and published posthumously in 1684. Alongside Lully, Du Mont is credited as the creator of the form - an opulent style of church composition for soloists and choir. On O Mysterium, Sebastien Dauce leads the Ensemble Correspondances in a program of Du Mont 's Motets & Elevations pour la Chapelle de Louis XIV.
