This year's Farm Aid concert will take place Oct. 4 at the Verizon Wireless Amphitheater in Maryland Heights, Mo., a suburb of St. Louis. Organizers made the announcement Thursday (July 16) during a press conference at the Soulard Farmers Market in St. Louis. Although special guests have not been announced, the show will feature Farm Aid board members Willie Nelson, John Mellencamp, Neil Young and Dave Matthews. Farm Aid members will have early access to tickets Friday (July 17) on the organization's Web site. Tickets to the general public go on sale July 25 through Live Nation. Farm Aid has raised almost $35 million to assist family farmers.
