The 5-release project The Lost Music of Canterbury: Music from the Peterhouse Partbooks is the capstone of a landmark project of international musical significance which presents extraordinary music from the last generation of medieval Catholicism in England. Judged by this music, Catholic culture remained vital and confident during this turbulent period. The fifth release in the set, released in 2017, was a Gramophone Editors Choice and Critics Choice, and was also shortlisted for the magazine's 2018 Early Music award. Fabrice Fitch called it "one of the discoveries of the year." The set includes mostly world premiere recordings and features masses by Nicholas Ludford, antiphons by Hugh Aston and Richard Pygott, the complete surviving works of Robert Jones, and the gifted though previously completely unknown composers Hugh Sturmy and Robert Hunt, and all but one of the surviving works of John Mason. The missing tenor parts have been supplied by Nick Sandon, who has dedicated much of his professional life to the Peterhouse partbooks, which were copied for Canterbury Cathedral in 1540 and are now named for the college currently housing them, Peterhouse Cambridge.
