The 27th annual Farm Aid festival is set for September 22 at Hersheypark Stadium in Hershey, Pennsylvania.  Farm Aid founders Neil Young, John Mellencamp, Dave Matthews and Willie Nelson will all be back to perform at the event, which benefits and supports independent, family-run farms throughout the U.S.  Other artists slated to play at the concert include Neil’s wife Pegi Young and her group The Survivors, Willie’s son Lukas Nelson and his band Promise of the Real, plus Jack Johnson ALO and others.

The full lineup for Farm Aid 2012 is expected to be announced in the near future.  Tickets for the event range from $35.75 to $99.75 and will go on sale on Friday at 10 a.m. ET.
