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.
