Charlie Daniels is pulling out all the stops for his 40th Anniversary Volunteer Jam. The lineup for the massive 2015 concert includes everyone from Trace Adkins to Ted Nugent to Billy Ray Cyrus.

The Volunteer Jam began in 1974 and has brought together some of country music's most iconic acts throughout its history. This year, thanks to overwhelming popularity and demand for tickets, it will move to Nashville's Bridgestone Arena, and the musicians slated to perform will definitely help fill all those seats. So far, the lineup includes Adkins, Nugent and Cyrus, along with Tracy Lawrence, Craig Morgan, Colt Ford, the Oak Ridge Boys, Michael W. Smith, Travis Tritt, Montgomery Gentry, the Kentucky Headhunters, the Outlaws and Lee Roy Parnell.

Proceeds from the Volunteer Jam will benefit the Journey Home Project, whose mission is to connect donors with organizations that meet the healthcare, education and career needs of veterans. Funds raised will also go towards the Predators Foundation, devoted to funneling the excitement of professional sports towards the needs of this community. The event will be hosted by Sean Hannity and Storme Warren.

The 40th Anniversary Volunteer Jam will held at the Bridgestone Arena in downtown Nashville on Aug. 12. Tickets are on sale now and can be purchased on Ticketmaster.
