Graffiti has come a long way in the past 30 years. Once an illicit juvenile pastime that drew the scorn of anyone over the age of 20, it has arguably become the most vibrant and visible of all modern forms of art. The style is now a primer for an ever-expanding niche dubbed "urban art," and has spawned hipster superstars such as Jean-Michel Basquiat, Doze Green, and San Francisco's own Berry McGee (who currently has a prominent piece displayed in SFMOMA). Haight Street's Future Primitive Sound (art collective, record label, gallery, store) not only provides the most comprehensive selection of graffiti supplies in the city -- including coveted Montana spray paint -- but it also features rotating exhibits of the finest urban artists in the world. Recent shows have included European graffiti pioneer and icon Mode 2, S.F. muralist extraordinaire Brian Barneclo, and NYC street legend Cycle. Their work proves that graffiti isn't just for vandals anymore.
