The programme of the latest recording by the distinguished choir 441 Hz brings together works by composers from a wide range of cultural traditions, from Scandinavia to the Philippines. Their shared expressive thread is a meditation on the phenomenon of light-it's symbolism, radiance, and transformative power. These composers write for mixed choir, enriched here by the subtle colours of violin, Tibetan singing bowls, handbells, and even water-tuned glasses.

Yet for all it's imaginative scoring, the programme is far removed from the world of avant-garde experiment. Instead, it unfolds in a language of luminous harmonies, deeply affecting solo voices, and expansive musical forms, creating an atmosphere of serenity and inward reflection.
