Insiders always knew that the daughter of a ballet-dancing Austrian aristocrat and a British MI6 agent (raised in a “nutty” commune before being educated in a convent) was far more than just a disposable muse. Faithfull was a rebel poet and a radical freethinker, much wilder, more anarchic and better read than the “straight” boys in the band she inspired. As the Stones became corporate purveyors of dad rock, mocked by the punks (“No Elvis, Beatles or the Rolling Stones/ In 1977,” sang the Clash) Faithfull came back from a suicide attempt, heroin addiction and anorexia to push ahead into new sonic terrain with her brutally, filthily brilliant 1979 album Broken English.
