Sir Michael Tippett's great masterpieces—Boyhood's End and The Heart's Assurance—are coupled here with some of his editions of songs by Henry Purcell, and Benjamin Britten's companion piece to Boyhood's End—Canticle 1. Superbly performed by John Mark Ainsley and Iain Burnside, an added treat is the performance of Tippett and Bergman's edition of Pelham Humfrey's setting of John Donne's A Hymn to God the Father.
