The Masked Dancer is most likely performing a "legong" dance from Indonesia. This Balinese dance is an offering to dieties.

One of these dances tells the story of how the God, Siwa, turned his wife into a corpse-eating witch. The God pretends to be sick and to test his wife's faithfulness, sends her to Earth to bring milk back to him. While on Earth she meets a handsome cowboy (Siwa in disguise) who says he will trade the milk for sex.

She eventually gives in and two daughters are born. Naturally this angers Siwa, who turns her into the witch - a Durga - who is forced to dig graves. The daughters are sent to Earth and become gods of dancing.

Unfortunately, it's difficult to find information on this particular painting because it shares a name with a Fox TV show.
