We used to call the 1% the ruling class, but America's never felt comfortable using that terminology. It was taboo to talk about class war. Americans are okay talking about it like this; everyone wants to be part of the 99%, even the cops are like, "No, no, man. I'm part of the 99% too." No one wants to be part of the 1%.

Street art is about as religious as I get - that's my faith, that even if people screen it out and didn't think they saw it, they did. Even if it was for a split second, it's become part of them and it's affecting them somehow.

Art makes people do a double take and then, if they're looking at the picture, maybe they'll read the text under it that says, "Come to Union Square, For Anti-War Meeting Friday." I've been operating that way ever since - that art is a means to an end rather than simply an end in itself. In art school we're always taught that art is an end in itself - art for art's sake, expressing yourself, and that that's enough.

Poster art was always my way of being involved in the conversation. So it wasn't just a one-way conversation with the police yelling at us or freaking us out. Street posters allowed you to have the last word.

I don't even believe in magic, or ghosts or anything like that, and yet in a city like New York, on the subway, I definitely see ghosts and art seems to have some magical properties.

The unusual thing about doing street poster art - or something with a conscious social critique in it - is that the artist thinks they're a little in control, focusing and trying to make a specific point. But even then, when you look at it a few years later, you realize you were just working through some of the usual feelings you were going through during that time.

When I was younger, when I was a teenager, the work was more satirical and funny and cartoony. And part of it was chops - if you have a more limited repertoire of stick figures and cartoon characters, they lend themselves more to humor than to tragedy.
