Margaret Rizza's Mary Slept sets text concerning the Annunciation and the Incarnation from the book The Ascent to Truth by the Trappist Monk, Thomas Merton.
Margaret Rizza began composing in 1997, her contemplative choral music being widely acclaimed not only in the UK but also abroad. When commissioned by Harry Christophers to write the choral composition for The Sixteen in 2007, Margaret embraced a new idiom in writing, that of 'Classical Contemporary'.
