Nicholas O’Neill composed his setting of 'Ave Verum' corpus in 1994. It's a modern setting of 'Ave Verum Corpus ' a hymn originally for the feast of Corpus Christi that dates back to the 13th Century and has been set time and time again by composers ranging from Byrd to Mozart to Lizst.
O'Neill's setting is for for eight voices and grows from a single note, slowly and gradually O'Neill paints a picture of suffering and redemption. It's sung here by the Schola Cantorum of Oxford under their conductor Jeremy Summerly. You'll find the mp3 file, text, and a translation to English below the fold.
