Graffiti Fine Art in Brazil

Just got back from an expo called "Graffiti Fine Art" taking action in one of the greatest free and contemporary museums in the city, MUBE.
(note: MUBE is located at the richest neighborhood in SP, Jardim Europa.)
As I was appreciating great artist's works, such as Anjo, Cern and Nove a traditional family came by (clearly the were doing an Easter Cultural Program or so) and started praising, out loud, for them.
Anyway, funny is: what if we all were under some bridge,  would they even notice those works? And if they did, what would they say?
(...)

Personally, I strongly believe in street culture and think pretty interesting that Grafitti is now positioned asFine Art and that  brazilian folks are being recongnized for it.
But above all, i believe in free expressions, whatever they may be.

So here goes my GOOD tought i'd like to share: pay close attention to expressions that are happening right now on the streets of your own city, and try to understand them.

Just don't wait for it to be in a museun.
They might not.

;)
cheers.
