Inspired by being gifted the excellent "The Conversations: Walter Murch and the Art of Editing Film", I wanted to ask you guys if you knew of any other very illuminating books on the creative process viewed on the interior of the artist. Obviously, your tastes in film (or hell music/literature as well, if you also have recommendations for those artistic domains) will shape your answers, but I want to make it clear that I am not interested so much in a compendium of facts or a biography. It really has to be a personal and interesting account on the nature of their work, and how they get about creating a piece of art. I have about 75$ in amazon gift certificates and figure I might as well use them for something positive and inspirational.
Many thanks!
