Martin Gayford wrote a book a few years ago about the experience of having his portrait painted by Lucien Freud. Man with a Blue Scarf proved to be not only an insightful, up-close-and-personal look at Freud, but also an engaging account of what it took to be one of his sitters. It’s one of my favorite books. Gayford has now focused his attention on David Hockney, transcribing a series of conversations he had with the prolific artist over more than a decade.

The portrait that emerges from the book is of an inexhaustibly inventive, restless, curious, and thoughtful artist. Now in his late eighties, Hockney has spent some seven decades not just painting and drawing, but thinking deeply about the act of looking. The book is filled with his insights on his own working methods, on other painters (Constable, Fra Angelico, Picasso, Van Gogh and many more), his fascination with new technologies, and the tireless determination to see clearly and record faithfully. It’s not in any sense a conventional biography, but Gayford’s clever and sensitive questioning tells you more about the personality, passions, and compulsions of this extraordinary painter than a traditional account might.

A Bigger Message is a book for Hockney fans for sure, but also for anyone interested in the mind and work of a great artist.
