(Wikipedia) - The Shiraz Arts Festival was inaugurated by Queen Farah Pahlavi on Sep, 11, 1967. The Shiraz-Persepolis Festival of Arts was an arts festival held annually from 1967 to 1977 in Shiraz sponsored by National Iranian Radio & Television. The festival included music, dance and theater, performed in the ruins of Persepolis and other attractions of the Fars Province.
The main focus was on traditional Iranian music, music of East Asia, and classical western music.
The cultural event attracted national and international artists, including Peter Brook, John Cage, Joseph Chaikin, Merce Cunningham, Jerzy Grotowski, Bismillah Khan, Vilayat Khan, Ram Narayan, Yehudi Menuhin, Gordon Mumma, Parisa, Arthur Rubinstein, Valda Setterfield, Ravi Shankar, Uma Sharma, Karlheinz Stockhausen, Shuji Terayama, David Tudor, and Iannis Xenakis.
During the 11th Shiraz Arts Festival in 1977, one of the longest live shows in the history of theatre called the Ka Mountain was performed in Shiraz which lasted for 164 hours and 47 performers acted continuously.
Following the Iranian Revolution, the festival was discontinued but other similar activities nevertheless more appealing to Iranian cultural heritage such as Day of Hafez on 20th of October take place in Shiraz every year.
