I don't know about other places, but in Europe, almost every major city has a Batucada Samba band. I've played in several, in Ghent, Brussels, Uppsala and Berlin, and I miss it. Anyone interested in forming one here or elsewhere in China? I'd be ready to move for this. Not only do I think it a great way to bring some life to the streets of Kunming, but it could also be pretty much a self-supporting gig.
Of course, we'd need to get instruments (although you get a long way with disassembled drum kits) and a maestro confident enough to lead a band like this. Technically, you can start playing from 5 people, but the more the merrier, as long as it remains tight.
For those who don't know what it is, it's simply percussion-only music with Brazilian/African roots and played by a batería (band) where each member carries one or more percussion instrument(s). A maestro (leader) manipulates the music as he sees fit or to play the crowd by giving signs and provoking responses to calls. When played well, it gets the crowd (and the musicians) into a sort of a trance.
Watch these vids, but imagine a way fuller sound.

Sometimes you can sing/play a small ukelele-like guitar to it:
