"The last outlaw of visual disciplines: Graffiti and unsanctioned art—from local origins to global phenomenonIn recent years street art has grown bolder, more ornate, more sophisticated and—in many cases—more acceptable. Yet unsanctioned public art remains the problem child of cultural expression, the last outlaw of visual disciplines. It has also become a global phenomenon of the 21st century. Made in collaboration with featured artists, Trespass examines the rise and global reach of graffiti and urban art, tracing key figures, events and movements of self-expression in the city’s social space, and the history of urban reclamation, protest, and illicit performance. The first book to present the full historical sweep, global reach and technical developments of the street art movement,Trespass features key works by 150 artists,and connects four generations of visionary outlaws includingJean Tinguely, Spencer Tunick,Keith Haring, Os Gemeos, Jenny Holzer, Barry McGee,Gordon Matta-Clark, Shepard Fairey, Blu, Billboard Liberation Front,Guerrilla Girls and Banksy, among others. It also includes dozens of previously unpublished photographs of long-lost works and legendary, ephemeral urban artworks."
