England

Tim Crouch may not be a household name but he's a peach of a theatre-maker: conceptual without being obscure; experimental without losing the plot, or indeed faith in the power of words to move you. Like his previous original works 'An Oak Tree' and 'My Arm', this new show stands at an unexpected angle to the world and illuminates it. Crouch performs this duologue with one of Shunt's most talented founders, Hannah Ringham. It begins with the pair acting as oddly benevolent and intense art guides in the white gallery space. But soon they're guiding us into the inner space of a man/woman who desperately needs a heart transplant. Crouch's singular virtue is to make you look, with your mind's eye, as intently and meditatively as you might at any old master. Stripped of the paraphernalia of a set - and even of the identification of one actor with one part - your imagination is the theatre in which the thickening walls and failing beat of the protagonist's heart (aided by Dan Jones's excellent, ambient sound) is vividly displayed. Bring flat shoes and an open heart.
