for SATB and pianoO Guiding Night is a colourful and evocative setting of the text 'The Dark Night' by 16th-century Spanish mystic/poet St John of the Cross. Williams's setting really gets to the heart of the words, conveying a range of emotions from hushed excitement to joyous rapture. Sumptuous harmonies and a strong sense of narrative are combined with charming piano interludes in an almost rhapsodic work, which would stand out in any concert.
