The Church of Stop Shopping is an activist performance group based in New York City, led by Reverend Billy, the stage name of Bill Talen. Using the form of a revival meeting, on sidewalks and in chain stores, Reverend Billy and his gospel choir exhort consumers to abandon the products of large corporations and mass media; the group also preaches a broader message of economic justice, environmental protection, and anti-militarism, protesting sweatshops and the Iraq War. Though it continues its street theatre activities, the Church has also appeared on stage and has toured internationally. [wikipedia]
