Artist Bob and Roberta Smith was recently appointed by Commissions East to oversee a project in which five artists were commissioned to create site- specific projects to transform open spaces in South Essex. Art U Need: My Part in the Public Art Revolution is an intimate account of this project, written in diary form. With sensitivity, candour and a great deal of humour, Bob Smith, and his alter ego, Roberta, ponder the nature and place of public art in today s world.
