Ziad's first artistic work was "Sadiqi Allah" (My Friend God), a collection of writings between the years 1967 and 1968 when he was in his teens. In 1973, at age 17, Rahbani composed his first music for Fairuz. Assi Rahbani, his father, was hospitalized and his mother Fairuz was to play the leading role in Al Mahatta by the Rahbani brothers. Mansour Rahbani, his uncle, who had written the lyrics of a song about Assi Rahbani's forced absence, gave Ziad the task of composing its music. The song "Saalouni El Nass" (People Asked Me) gained Ziad recognition.
