Michael White on a clandestine retelling of William Byrd’s 16th-century Mass settings and a Buddhist interpretation of Bach’s Passions.

It’s as well that liturgy, although theatrical by nature, isn’t always so dramatic, otherwise the risk of heart attack in church attendance would be worryingly high. But this is how it was last month at an event to mark four centuries since the death in 1623 of the composer William Byrd – with a performance of his five-part Mass staged as immersive theatre.
