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. 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. "Art U Need" is a refreshing addition to the art debate, providing a unique insight into the workings of the artist's mind. Through his remarkably honest approach, Bob and Roberta Smith manages to encapsulate the larger issues surrounding the roles of funding bodies, self-expression and, of course, the public, in public art today.
