Born Declan Patrick MacManus, Elvis Costello was raised in London and Liverpool, grandson of a trumpet player on the White Star Line and son of a jazz musician who became a successful radio dance band vocalist. Costello went into the family business and had taken the popular music world by storm before he was twenty-four. "Unfaithful Music" describes how Costello's career has endured for almost four decades through a combination of dumb luck and animal cunning, even managing the occasional absurd episode of pop stardom. The memoir, written entirely by Costello himself, offers his unique view of his unlikely and sometimes comical rise to international success, with diversions through the previously undocumented emotional foundations of some of his best known songs and the hits of tomorrow. It contains many stories and observations about his renowned co-writers and co-conspirators, although Costello also pauses along the way for considerations on the less appealing side of infamy.
