In this unique rock-and-roll journey, Dave Grohl and the Foo Fighters venture to eight cities - Chicago, Washington, D.C., Nashville, Austin, Los Angeles, New Orleans, Seattle and New York City -- and record a cut from their new album in each of these iconic places. Along the way they meet with legends like Buddy Guy, Joan Jett, Willie Nelson, Dolly Parton and Chuck D, among others, to get to the heart of American music in all its forms.
