Imagine a carol concert with a magical difference. In the deep, still darkness of St Martin-in-the-Fields, only candles pierce the winter twilight. And then, upon the silence, comes the luminous sound of a choir in harmony: familiar melodies, wondrous discoveries and readings to make you smile as well as reflect.

Ex Cathedra’s Christmas concerts are both an undiscovered secret and a cherished tradition, unmistakably seasonal but aimed – in these fast and noisy times – at the still, quiet heart of the season; the mystery as well as the merriment. The true, ancient magic of Christmas? We just know that once experienced, it’s never forgotten.
