The leader of the Catholic church has given Deutsche Grammophon officials special permission to capture the world-premiere recording of the original version of Allegri's Miserere within the walls of the chapel in Vatican City's Apostolic Palace, using his Sistine Chapel Choir.

The album, Cantate Domino, which will be released later this month (Sep15), will also feature music written during the Renaissance.

Choir director Massimo Palombella tells the BBC, "After an intensive period of study and scholarship of the sacred music in the Renaissance and its aesthetic pertinence, we have arrived at the point of making the first commercial recording, in this remarkable building."

Pope Francis will receive the first copy of the album.
