A native of England's Hertfordshire region, Tilbrook was trained at York University and later, on scholarship, at the Royal Academy of Music, where she won a host of accompaniment prizes and became an Associate in 2009. She made her debut at Wigmore Hall in 1999 and has since joined a variety of singers and top chamber music groups at festivals and major concert hall appearances.
Tilbrook has worked with an impressive range of singers and instrumentalists, most of them British. These have included Lucy Crowe, with whom she made her debut at Carnegie Hall in New York, Mark Padmore, Iestyn Davies, Nick Daniel, Jack Liebeck, and Barbara Hannigan. In television concerts mounted by the Welsh National Opera she has performed with the likes of Bryn Terfel, José Carreras, and Angela Gheorghiu. Her most lasting collaboration has been with tenor James Gilchrist, with whom she has explored the 20th century English song repertory. Their recording of Ralph Vaughan Williams' On Wenlock Edge was a finalist in the 2008 Gramophone Awards, and they have recorded song cycles by Gerald Finzi, Kenneth Leighton, and Benjamin Britten, as well as earning an Editor's Choice nod from Gramophone for recordings of Schubert's song cycles. As a chamber player she has worked with the Sacconi, Barbirolli, and Elias string quartets. As a rehearsal pianist and coach she has worked with top-flight organizations, including the London Symphony Orchestra and the Royal Opera. She has also played Baroque continuo, and directed a Buxton Festival performance of Telemann's Pimpinone from the harpsichord.
Tilbrook's catalog of recordings is large and was augmented in 2018 by a viola version of Ralph Vaughan Williams' Six Studies in English Folksong, performed with violist Philip Dukes, which appeared on the Chandos label. ~ James Manheim, Rovi
