Prime Passage: Underworld by Don DeLillo

The graffiti artists of 1970s New York City...

"But you have to stand on a platform and see it coming or you can't know the feelings a writer gets, how the number 5 train comes roaring down the rat alleys and slams out of the tunnel, going whop-pop onto the high tracks, and suddenly there it is, Moonman riding the sky in the heart of the Bronx, over the whole burnt and rusted country, and this is the art of the back streets talking, all the way from Bird, and you can't not see us anymore, you can't not know who we are, we got total notoriety now, Momzo Tops and Rimester and me, we're getting fame, we ain't ashame, and the train go rattling over the garbagy streets and past the dead eye windows of all those empty tenements that have people living in them even if you don't see them, but you have to see our tags and cartoon figures and bright and rhyming poems, this is the art that can't stand still, it climbs across your eyeballs night and day, the flickery jumping art of the slums and dumpsters, flashing those colors in your face--like I'm your movie, motherfucker." pg.441
