Commemorating 30 years since the passing of avant-garde writer and artist Shuji Terayama, this exhibition brings together artifacts from his 30-hour street play, "Knock."

In 1975, Terayama and his theater troupe used Tokyo's Asagaya neighborhood in Suginami Ward as the stage for this work, which took cues from everyday life. The experimental performances took place throughout the day and included a "Sky Walker," who used a unique device to keep himself suspended above ground. Accompanying this detailed documentation of "Knock" is an overview of Terayama's other photographic and written works; July 6-Oct. 27.
