performance of what appears to be a traditional Indonesian cultural performance

performance of what appears to be a traditional Indonesian cultural performance. A group of performers, wearing black shirts and pants, as well as ornate headdresses resembling horses, are interacting on the ground. Some performers are writhing on the ground while holding the headdresses. The environment appears to be outdoors, possibly in a village setting, with buildings in the background. The performance appears to be taking place near a crowd of onlookers, some of whom are seated under a canopy. The lighting is bright, suggesting it's during daylight.
