"This is the biggest art movement in the history of human kind." I bet you don't know what the medium is.
"Bomb It," the new documentary about the rise of the graffiti movement in urban regions throughout the world, shows the explosion of underground "tagging" as both an art, and a form of communication (some would argue that any art is a form of communication, which I would agree with). Be it Barcelona, New York, Jo'burg, Berlin or Chicago, this movement has gone way beyond the cultural name-tags ascribed to it years ago yet is still true to its roots. Nor is it dominated by criminals, drug addicts, or delinquents. The artists are legitimate and their work is magnificent.
While I do question the painting of personal property (like cars and homes) I agree that the public space available for this type of art is actually extremely limited since so much of public space is actually reserved for advertising (sides of public buses, highways, etc). So, like any American people are taking it back. I don't blame them.
On a whim, I actually caught one of the original graffiti culture/ hip-hop flicks from 1983 called "Wild Style" last weekend. It should be fun to do a comparison of the two after seeing Bomb It.
I'll be checking it out this weekend and maybe you will too.
