O Sacrum Convivium! (HL 50565707)

For chorus of four part mixed voices. The original published score states “with organ accompaniment ad libitum.” Messiaen later in life designated the work for mixed choir a cappella, but the score was not revised. Thus the piece is often performed without accompaniment. The text is by St. Thomas Aquinas (1225-1274), used as an antiphon for the feast of Corpus Christi.
