The Arundel Choirbook (also called the Lambeth Choirbook), one of the most important extant collections of English polyphony, is 500 years old this year. To mark this significant milestone, the Iken Scholars are collaborating with Lambeth Palace to record seven previously un-recorded works. As well as making these recordings publicly available, it is hoped there will be a number of performances of these pieces throughout the year.
