Britain's best-selling choir of the 21st Century, the Sixteen, releases a new album of music inspired by Virgin Mary. Harry Christopher's, the most prolific choral conductor of modern times, directs the choir performing a disc of Marian songs ranging from medieval composers like Palestrina, and Lassus through Bruckner and Liszt, all the way to modern times, including a world premiere work by Margaret Rizza, Ave Generosa.
