Facing the dark with hope

Having exhibited at the ICA as a student during the early 1980s, David Johnson was prevented from fully pursuing his artistic passions by illness. But now he's bounced back and presents his first major show since recuperating, which features a mixture of both old and new works.

Using found objects such as boats, beds and baths, Johnson explores the interior and exterior worlds, examining the complex metaphysical relationship between reality and how we perceive it. His new material continues these themes by creating what he refers to as 'apparent sources of light'. One example is Facing The Dark, which, with its bricked-up window and light projected from above, gives the impression the light is coming from the window itself to demonstrate the way our own perceptions are projected on to the world around us.

Deep and meaningful stuff, but if it all seems like too much of a brain-strain, try relaxing in the tranquillity of his other works, such as Ocean, where it's hard not to be soothed by images of the starry night sky being beamed down on to a pool of milk in the bottom of a rowing boat. Let's hope they don't let it curdle.

Until Mar 25, The Roundhouse, Chalk Farm Road NW1, daily 11am to 6pm, except Thu to Mar 10 11am to 8pm, free.
