Perhaps more than any artist of his generation, Julian Opie has taken his art beyond the gallery walls and out into the mainstream of cultural life, testing his ideas in a wide variety of different media. Author Mary Horlock surveys his career, beginning with the early painted metal sculptures of everyday objects, encompassing the 3-D evocations of the urban landscape, and finishing with the powerful graphic style evolved in recent years that has transferred to billboard posters, road signs, LED screens and album covers. In a series of interviews Opie reveals much about his motivation and vision, offering fresh insight into his sources of inspiration as well as his working methods.
