Elvis Costello’s memoir, “Unfaithful Music and Disappearing Ink,” details how his career has persevered for nearly forty years. By a stroke of pure luck and slyness of character, he enjoyed the odd ridiculous moment of pop glory. Composed with the same distinct style as his songs, the book presents Costello’s singular perspective on his improbable and occasionally humorous ascent to global acclaim. It also explores the emotional underpinnings of some of his most well-known songs that have never been before revealed and makes predictions about future hits.
