This setting of ‘O lux beata Trinitas’ (ascribed to St Ambrose) weaves together a range of vocal styles and textures to build gradually from the quietly pensive opening section to a rousing unison declamation on the words ‘Deo Patri sit Gloria!’. With the hallmarks of Matthew Martin’s inimitable voice, this anthem will prove a powerful choice in evensong or as part of a mixed choral programme.
