Through his musical life, Dariush has worked with lyricists like Iraj Jannati Ataee, Ardalan Sarafraz, and Shahriar Ghanbari, as well as renowned composers such as Ahmad Pejman, Farid Zoland, and Varoujan. He also has considerable respect for traditional Iranian poets like Rumi and Hafez. Dariush participated in two films as an actor before the Islamic Revolution, Yaran and Faryad Zir e Ab. In the late '70s Dariush was hospitalized after being sprayed with a caustic substance in an attack by an apparently deranged fan. During treatment he used morphine to relieve the pain, and became addicted. Dariush suffered in this condition until recent years when he was finally able to free himself from the grip of addiction with the assistance of specialists; subsequently, Dariush and two physicians founded the Ayeneh Foundation, which has seen considerable success in its treatment of addicts. Dariush has also developed and participated in radio and TV programming aimed at empowering people to confront and overcome substance abuse.
He is also a member of Amnesty International, and has received several awards from the human rights organization. (Dariush had been imprisoned before the Islamic Revolution because of his what he has referred to as his deep beliefs.) After the Revolution, in 1981 he left Iran for England. In a recent international festival of music videos in Bahrain, he was recognized for his representation of contemporary Iranian music.
