Often at the time of the full moon, I cycle to the Severn to sleep on the edge of the river. There’s something compelling about the place, about the act of sleeping on the ground, and feeling the energy from the earth and the pull of the tidal river. Using pencil, watercolour and spit on gesso boards, I make the drawings at night. One of these drawings is called Ground Truth, a geographic term for a type of field research: going to a point located on a satellite image in order to verify and come to know that place.

Ground Truth and Deep Grief are currently showing in the Jerwood Drawing Prize 2011.
