Japanese psychedelic noise rock pioneers Les Rallizes Dénudés played this concert at Yaneura in Tokyo on 23 March 1981. The footage, resurfaced by an archival YouTube channel, documents the group led by Takashi Mizutani at the height of their live intensity — transcendent psychedelia meeting sonic assault. Echo Mandala shares the recording because it captures a foundational moment of Japan's underground psych scene outside any release cycle. Archive material, not news.
