It's mainly the idea sent to the western world that such events do happen in the East.
You would be surprised at how many people think it it is a purely American and European phenomenon.

Perhaps you wouldn't, but most people are.

This place is buzzing on the music scene...
From Deathmetal to Jazz it's all here. Even the buses have buskers who travel with the bus, Jakarta is a pretty mind-blowing place, but, at the heart of it it all comes down to their music. The jogja ensembles are equally awesome, traditional Indonesian instruments played at breakneck percussive speed (preferably on a Balinese beach with chilled beers) is surreal.
This is one place in the world that I recommend people do really try to see.
