For more than thirty years, the career of composer Etienne Moulinie was inseparably linked with the patronage of Gaston d'Orleans (1608-60), brother of Louis XIII. In his Melanges sur des sujets chretiens, which he regarded as his magnum opus, Moulinie claimed the right to a compositional freedom that would ''purify music and make it wholly chaste.'' Some of the finest pieces from the collection feature on this recording by Sebastien Dauce's Ensemble Correspondances, showing just how successfully the composer achieved his aim.
