Doubly circumscribed as part of both this year's Norfolk & Norwich Festival and the Olympian London 2012 Festival, How Like An Angel is a site-responsive work, made by the Australian contemporary circus giants Circa in collaboration with the vocal ensemble I Fagiolini, devised for performance in cathedrals. Circa have been seen in the UK before with their compilation show and the cynically stylish Wunderkammer, but however you feel about the company's previous work Sideshow judges this is one to see – for the occasion and the ambiance, but also to support a circus show that's pulling the sort of production coups (it's in Norwich Cathedral!) normally reserved for contemporary music or dance.
