Neil Young, Willie Nelson and John Mellencamp will perform.

The 19th annual Farm Aid benefit will be held Sept. 30 at the Tweeter Center in Camden, N.J., just across the Delaware River from downtown Philadelphia. Farm Aid co-founders Neil Young, Willie Nelson and John Mellencamp will perform, as will Dave Matthews. Tickets go on sale July 14 to members of the FarmYard club and July 22 to the general public.

Young announced the details today (July 6) during a press conference at Philadelphia's Reading Terminal Market. "It is unfortunate that we have to continue doing this," he said. "I really hope that we don't have to do Farm Aid forever."

To date, Farm Aid has raised more than $29 million in support of family farms, locally grown food and fair pricing. The Camden location was chosen due to the high amount of farmers' markets in the surrounding area.

"Family farmers are our best choice for good, fresh, wholesome foods," Young said. "When you choose local, sustainable, humanely raised, or organic food from family farms, you are keeping family farmers on the land."
