were a Japanese experimental music ensemble founded in 1969 by former Group Ongaku leader and Fluxus member Takehisa Kosugi.
The rest of the group were several years younger than Kosugi, and were all inspired by the spirit of the day.
They chose mainly to perform their music outdoors, often on beaches and hilltops, creating spontaneously improvised drones (compare with Dronology), often using standard musical instruments, albeit in unconventional ways (e.g., a bowed double bass placed flat on its back).
The group's sound was heavily reliant on electronic processing, particularly delay effects.
