I don't know???
It's like Banksy(No comment if some of them are). To me he is a real artist. Talented... However I fear that this whole street art thing is becoming repetitive. What do I know. I for the most part hate modern art.
Man you need to watch some real graff flicks then there are plenty of good ones out there but a lot have been ripped from vhs so quality sucks, check out londons white trash or solvent abuse, here is the best part from solvent abuse, ATG tearing shit up
Although the're not really documentaries more just graff flicks
And nah mate there isn't an official release date anywhere atm
