VIDEO : Hank Williams Jr., Chris Stapleton Anchor CMA Fest Lineup

A rowdy icon and the firebrand of the traditional-country resurgence are among the performers announced for CMA Music Festival. Hank Williams Jr. and Chris Stapleton will each perform sets at Nashville's Nissan Stadium during Night Two of CMA Music Fest in June. Eric Church, Carrie Underwood and Sam Hunt round out the Friday night lineup, while Miranda Lambert, Dierks Bentley, Jason Aldean and Rascal Flatts are scheduled for Thursday evening's kickoff. They'll perform a string of eight shows beginning August 5th in Tampa. They don't rehearse a whole lot, and I don't either," Williams tells Rolling Stone Country.
