Farm Aid’s 2009 concert will be held Oct. 4 at the Verizon Wireless Amphitheater in Maryland Heights, MO.

Willie Nelson, Neil Young, John Mellencamp and Dave Matthews are scheduled to appear, and other artists will be announced soon.

Tickets will go on sale 10 a.m. Saturday, July 25, and are exclusively available at livenation.com, the Verizon Wireless Amphitheater Box Office, participating Blockbuster stores or by calling (877) 598-8703.

“Farm Aid has deep roots in the Midwest that reach back to our first concert in Illinois in 1985,” says Nelson, the organization’s president. “I’m looking forward to bringing my friends together on the Farm Aid stage to celebrate family farmers and the crucial work they do. Farmers do so much more than bring us the good food we all want to eat. America needs family farmers to revitalize our economy and make our country healthy.”

Presented by Horizon Organic, the event will once again feature HOMEGROWN concessions, with foods from regional family farms and local organic growers. The HOMEGROWN Village will host hands-on activities that give concertgoers a chance to meet family farmers and get their hands dirty.

“Family farmers are innovative entrepreneurs who safeguard our food, environment and health,” says Carolyn Mugar, Farm Aid’s executive director. “Since the beginning, Farm Aid has worked with family farmers in the Midwest to keep them on the land, especially in the face of factory farms that have threatened to take over food production. At Farm Aid, concertgoers will reap the benefits of this work and will experience food grown by Missouri’s family farms.”
