(AP) - Imagine Dragons, Kacey Musgraves, Jack Johnson, Old Crow Medicine Show and Mavis Staples are among the acts who will play this year's Farm Aid. The concert will be September 19 in Chicago.

The lineup also includes Farm Aid board members Willie Nelson, John Mellencamp, Neil Young and Dave Matthews.

This will be the 30th anniversary of the first Farm Aid, and Nelson says this year's show will celebrate "the impact we've had and rally our supporters for the work ahead."
