Sparky, illuminating and entertaining – a decade’s worth of conversations between David Hockney and art critic Martin Gayford that explore via anecdote, reflection, passion and humour the very nature of creativity.David Hockney is possibly the world’s most popular living painter, but he is also something else: an incisive and original thinker on art. Here are the fruits of his lifelong meditations on the problems and paradoxes of representing a three-dimensional world on a flat surface. How does drawing make one ‘see things clearer, and clearer, and clearer still’, as Hockney suggests? What significance do different media – from a Lascaux cave wall to an iPad – have for the way we see? What is the relationship between the images we make and the reality around us? How have changes in technology affected the way artists depict the world? A Bigger Message: Conversations with David Hockney is out now on Thames & Hudson.
