Ziad Rahbani
His demanding career eventually started taking a toll on his health. By the late 1970s, Rahbani's mental health began to deteriorate. Fairuz and the Rahbani Brothers agreed to end their professional and personal relationship in 1979, which also included Fairuz separating from Assi Rahbani. Fairouz began to work with a production team led by her son, Ziad Rahbani, and the Rahbani Brothers composed for other artists.
