Charlie Daniels' 40th Anniversary Volunteer Jam announced Tuesday (June 30) it has added industry vets Wynonna Judd and Terri Clark to its extensive lineup.

The concert, which will take place Aug. 12 at Nashville’s Bridgestone arena, features a long list of other stars, including Trace Adkins, Alabama, Colt Ford, Montgomery Gentry, Ted Nugent, Travis Tritt, and of course, Daniels, and benefits U.S. veterans through the Journey Home Project.

The Journey Home Project was founded in 2013 by Daniels and his long-time manager David Corlew, and serves to connect donors to organizations that provide services like health care, education and career help to U.S. veterans.

"It’s really something to see my music peers and friends come together this year to perform with little incentive other than to help raise funding and give back to those who have served,” Daniels says in a news release. "Few sacrifices are greater than those of our U.S. military, so it makes me proud to have witnessed this event come together in such a big way in 2015. We as U.S. citizens can never repay military members and veterans for what they have and continue to do for us, but I hope at least this concert can serve a small role in showing them our great appreciation."

Daniels has hosted the Volunteer Jam since 1974. This year's event will also include performances on the Henry Rifles Stage on the Bridgestone Plaza that will be free and open to the public from 4-7PM. It will feature Natalie Stovall & the Drive, the Grascals, American Hitmen and more.

Tickets are available for purchase at Ticketmaster.com or the Bridgestone Arena box office.
