..sorry...
In my opionion, graffiti need all elemante to survive itself. It needs it fantastic piecers, or wildstyle kings, or straight letter bandits, the all around kids, the throwie mongers, the new kids, the "street art" people, the stencilers, the gang graff, the scribblers, the taggers and anybody else.
Graffiti is a fuckn free for all.
Who the fuck is anyone to say about what someone else does to some wall in the middle of the night.(or day if your fresh), Everybody get in the work no matter how you get it in. Live for it and be about it. Its your own self out there and do it for you.
Fuck anything else
