Book excerpt: Complicated Shadows paints a detailed and accurate portrait of an intensely private and complex individual. It draws on nearly 50 exclusive interviews with schoolmates, pre-fame friends, early band members, journalists as well as members of The Attractions, producers, collaborators and musicians from all stages of his life and career. Thomson also unearths many previously unknown details about Costello's early years and his personal life, as well as examining his entire musical output using the recollections of those who were there at the time, the majority of whom have never talked on the subject before.
