A series of shows of performance art entitled “John Cage Is Happening”, which has been arranged by 30 Iranian artists to mark the centenary of American composer John Cage at Tehran’s East Art Gallery. The performance art show has been inspired by Cage’s greatest music-theater work “Song Books” in July 2012, and I used his writings from his song books, with considering those sentences, I tried to show my illustrations with mix media (photography and collage) as an installation. My installation was there during the performances (two weeks) in a specific area at the gallery.
