Music by Morten Lauridsen occupies a permanent place in the standard vocal repertoire of the Twentieth-Century. His seven major vocal cycles – Les Chansons des Roses (Rilke), Mid-Winter Songs (Graves), Cuatro Canciones (Lorca), A Winter Come (Moss), Madrigali: Six "Firesongs" on Renaissance Italian Poems, Nocturnes (Rilke, Neruda and Agee) and Lux Aeterna – and his series of sacred a cappella motets (O Magnum Mysterium, Ave Maria, O Nata Lux and Ubi Caritas et Amor) are featured regularly in concert by distinguished ensembles throughout the world. O Magnum Mysterium, O Nata Lux (from Lux Aeterna) and Dirait-on (from Les Chansons des Roses) have become the all-time best selling choral octavos distributed by Theodore Presser, in business since 1783.
