The past decade has witnessed an explosion in the hybrid practice of "artistic activism," as artists have turned toward activism to make their work more socially impactful and activists have adopted techniques and perspectives from the arts to make their interventions more creative. Yet questions haunt the practice. Does artistic activism work aesthetically? Does it work politically? And what does "working" even mean when one combines art and activism? Æffect is rich with examples that demonstrate successful artistic activism, including Undocubus, an old bus with "No Fear" painted across its side that was driven across the United States by a group of undocumented immigrant activists; Journal Rappé, a video show created by Senegalese rappers who created long-form investigative reports by rapping the current news in French and Wolof; and war on Smog, a staged public performance piece by artistic activists in the city of Chongqing in Southwest China. In Æffect, Stephen Duncombe draws on twenty-five years of experience and more than one hundred in-depth interviews with artistic activists worldwide. More than a mere academic exercise, the theory, research, and tools in this book lay the groundwork for artistic activists to evaluate and strengthen their practice and to create better projects.
