In this remarkable book, a record of a decade of private conversations with art critic Martin Gayford, David Hockney reveals via reflection, anecdote, passion and humour the fruits of his lifelong meditations on the problems and paradoxes of representing a three-dimensional world on a flat surface. These conversations are punctuated by wise and witty observations from both parties on numerous other artists, and enlivened by shrewd insights into the contrasting social and physical landscapes of California, where Hockney spent so many years, and Yorkshire, the birthplace to which he has returned. Some of the diverse people he has encountered along the way – from Henri Cartier-Bresson to Billy Wilder – make entertaining entries into the dialogue.
