Graffiti represents an extremely young global underground subculture, it's the root of modern guerilla marketing and the core inspiration behind street art. This episode of "Crack and Shine" highlights Katsu, a graffiti vandal active in NYC. Katsu's campaign is unique within the graffiti world because while most vandals influence with traditional street tagging and murals, Katsu uses deeper conceptual strategies to promote the movement. To learn more about Katsu and other graffiti writers from New York such as Ket, Noxer, Veefer, Greg Lamarche (SpOne), Lewy BTM, Stephen Espo Powers and photographer Stephen K.Schuster, check out the book available here.
