Nadia and Lili Boulanger, each in her own way, made a lasting impact on the musical world of the twentieth century. Sometimes luminous and full of hope, sometimes more somber, all their works testify to a poignant humanity. Going beyond the melodies, Lucile Richardot, Anne de Fornel and the other artists assembled for this edition offer a multi-faceted portrait of the two composers, a form of musical narrative containing pieces that have never been published or recorded before.
