Cambridge is a city famed for its world-leading choirs of boy choristers - but ten years ago, St Catharine's College founded the first college-based choir for girls. In the latest Gramophone podcast the Music Director Edward Wickham talks to Gramophone Editor Martin Cullingford about that first decade, and about the choir's new recording 'Sing Levy Dew', a beautiful programme of music for upper voices by contemporary and 20th century composers, released on the Resonus Classics label.
