Following graffiti's early days on the streets of NYC and Philadelphia in the 60's and the commercial crossover of street art in the 70's, the art form has since exploded into a global revolution of creative expression. Roger Gastman's documentary reveals the growth of the wall-writing movement that would eventually transform the way we view our cities and redefine the notion of public art around the world. Narrated by legendary filmmaker John Waters, Wall Writers features unprecedented access to the forefathers of graffiti with CORNBREAD, TAKI 183, SNAKE1, and more than two-dozen others, along with testimonies from the journalists, historians and politicians who bore witness to the largest art awakening of the 20th Century.
