Willie Nelson's annual Farm Aid concert, now in its 25th year, promises a day filled with artists from all genres performing to raise money for farmers across America. Now, with the concert just one day away, Jamey Johnson has announced he will join the eclectic list of acts taking the stage in Milwaukee, Wis., for the day-long event.

Other artists performing during Farm Aid 25 include Kenny Chesney, Dave Matthews, Norah Jones, Amos Lee, The Blackwood Quartet, Randy Rogers Band, Jason Mraz and Amos Lee, as well as founders Willie Nelson, Neil Young and John Mellencamp.

Farm Aid 25: Growing Hope in America
marks a quarter-century of the tireless work of Willie, and others, to bring attention to the economic plight of farmers in the United States. And while co-founders Neil Young and John Mellencamp, have donated their time and energy to the worthwhile cause, it's Willie who quietly and tirelessly made it his life mission, without receiving many accolades for his efforts.

"It is very important we point out that I think Willie should get Nobel Peace Prize for Farm Aid," says John Mellencamp. "This thing has been going on 25 years ... I am very proud of Willie. Whoever does this Nobel Peace Prize should look at Willie Nelson. My contribution is from the neck down. Willie is the brains behind the outfit."

Farm Aid kicks off tonight (October 1) with a special concert by Drive-By Truckers at the Pabst Theater in Milwaukee, and the guys couldn't be more honored. "This was something we all felt strongly about doing," Truckers frontman Patterson Hood tells The Boot. "Anything we can do to show this cause is near and dear to our hearts, we want to do it."

The Farm Aid concert will be broadcast live on Willie's own Sirius XM radio station, Willie's Place starting at 2:00 PM ET.
