Nativite (for String Trio and String Orchestra) by Leon Mouravieff (1905-1987) is on a Christophorus CD (CHE 0051-2) of Concertante Russian Music that I've got. The piece is the first part of his triptychon La Mere, which would be followed by the movements Pieta and Notre-Dame de la Sainte-Sagesse. Nativite is a beautiful soothing piece, but I have been unable to find any recordings of the entire La Mere - nor any other recorded works by Mouravieff! Does anyone know if any such recordings are out there?
