The first major choral setting of The Diary of Anne Frank takes the teenager's remarkable and penetrating observations, written whilst hiding in an Amsterdam attic, as the basis of it's extraordinary and moving libretto. Whitbourn's music for this work has been described as "woundingly beautiful" (The Daily Telegraph). He reflects sounds of the Westerkerk bells and tunes heard on the radio in the Annexe, along with representations of Anne Frank's Jewish and German heritage, details that add to a score "whose respectful understatement is it's greatest strength" (The Times).
