What's traditional show is this?

So last time I went to Yogyakarta, my aunt said a few days after I left that it's a shame that I must left so early, because if I'm not I can watch the traditional show in Keraton. My aunt said it was a traditional dance show. She mentioned about one of the character, Rengganis ( I think it's a woman?) and Garuda, then another woman Rengganis fight to is a chinese princess? Or a commander? I'm not sure. I hope my details give you some clue.

What's the name of the traditional show?
What's the story about?
When it'll be held again?

Well, the show is called Rengganis. It is a traditional drama that originally came from Banyuwangi at the mataram kingdom age. Rengganis is a princess.

About the strory, it is taken from a book named Serat Menak. There are many stories in that book, unfortunately I didn't recognize the plot that you were saying (reffering to characters like Garuda(?) and Chinese princess(?), all I know is Rengganis herself, Prabu roro and Guparman)

Maybe you should read the Serat Menak, find it on the internet or any other sources to correctly identify the show.

The Jogjakarta tourism board website perhaps can give you clue when the show will be held again.

I'm no real experts in this but the name of the traditional show would be "Wayang Orang", a dance drama performed by professional dancer imitating a puppet of the character in the story.

I'm not sure about the story as there are thousands of stories performed using this method and this one is not a nation wide story but rather a specific JOGJA palace (keraton) stories. Some stories refer to historical events while some are just stories.

The Keraton conducts performance from time to time but this needs to be browse in the local daily newspaper
