Performed out of their new home in St George's Yard and incorporating a Routemaster bus with a sinister repaint, Psychological Art Circus' Illusions of Reference is inspired by the cloudy history of the Delphic Oracle and comes in two parts: first a live art installation, then a performance (featuring two PAC founders, Andrea Meneses Guerrero and Dagmara Bilon). The company come at circus from a slightly different direction to other UK practitioners, via corporeal mime and body-based live art, so it's worth checking out for something off the beaten track.
