Warhol (part two): Jeremy Deller and Shadows

In the second part of our Andy Warhol special, we talk to the British artist about meeting Warhol, his life-changing trip to the Factory and Warhol’s legacy. We also discuss Dia’s vast installation of the Shadow paintings (1978-79): are they "disco decor” as Warhol remarked, or one of the central bodies of work in his career, unifying many key themes and strands?
