But alphabetising any list of artworks, while useful in some ways, skews observance of the artist’s evolution. A more visible sense of a writer’s development might have resulted from a chronological or thematic approach. Then again, chronology brings its own stodginess and is its own distorting lens. Most writers are working in circles, not unbroken lines. Caveats aside, the book is to be celebrated as overdue, the most complete picture of this remarkable songwriter’s restless intelligence and achievement that we are likely to have.
