Keacak is a form of Balinese dance and music drama that was developed in the 1930s in Bali, Indonesia. Since its creation, it has been performed primarily by men, with the very first women's kecak group starting in 2006.
Kecak was originally a trance ritual accompanied by male chorus. In the 1930s, Walter Spies, a German painter and musician, became deeply interested in the ritual while living in Bali. He adapted it as a drama, based on the Hindu Ramayana and including dance, intended for performance before Western tourist audiences
