Operation Ceasefire, a "new coalition of concerned musicians," is "a part of the United for Peace and Justice September 24-26  weekend of action." Operation Ceasefire is a free music festival to stop the war in Iraq. 
"This event will be a centerpiece of what is expected to be 4 days of enormous protests in nation's capital in support of a full withdrawal of U.S. forces from the quagmire in Iraq. The concert will bring together musical acts such as: Thievery Corporation, punk rock and independent musicians LeTigre, Bouncing Souls, Ted Leo & The Pharmacists; country music artist Steve Earle, rock and soul band the Bellrays; latin musicians Machetres, socially conscious hip-hop groups The Coup and Head-Roc; and even long time activists Wayne Kramer of the MC5, Jello Biafra and Greg Palast will be involved in this event!
"With over 60% of the public currently opposed to the war in Iraq, this concert is a fun way we can all come together and demand that this Congress and this administration bring our troops home and start a well over due Ceasefire!"
