Leonard Cohen, Untold Stories: The Early Years tells of the extraordinary life of one of the world’s greatest musicians and literary icons, in the words of those who knew him best. This book chronciles his life from boyhood in Montreal to university, and his burgeoning literary career to the world of music, culminating with his first international tour in 1970. Posner draws on hundreds of interviews to reach beyond the Cohen of myth and reveals the unique, complex, and compelling figure of a real man.
