Concentrating on issues of the environment and ecology, Duncan's work transports situations into the gallery space that he has encountered while walking on the streets of his native Swansea and the rocky coves of the nearby Gower peninsula. His work, in this way, follows a history of artists using the walk and the idea of the walk as starting point for art making, responding to their local area through their work. While Duncan's work does indeed point to this rich history of art production, it also speaks of art's fundamental ability to question the world around us, making, as it does, the apparently familiar, unfamiliar.
