A rocker (Eric Church), a legend (Alan Jackson), an Aussie (Keith Urban) and many more country artists have been added to the 2015 ACM Party for a Cause lineup.

Church, Jackson and Urban will be taking the stage at the third annual, two-day outdoor music festival on the weekend leading up to the 2015 ACM Awards, along with the just-announced John Anderson, Deana Carter, Brandy Clark, Brett Eldredge, Sara Evans, Brantley Gilbert, Hunter Hayes, Ashley Monroe, Kip Moore, David Lee Murphy, Joe Nichols, Jake Owen, Reba McEntire, Marty Stuart, Cole Swindell, Brooks & Dunn, Lady Antebellum and the Band Perry.

In early March, the Academy of Country Music announced the first round of Party for a Cause performers, which includes Miranda Lambert, Luke Bryan, Florida Georgia Line, Kenny Chesney and many more. The complete lineup, including additional performers and duet collaborations, will be announced soon.

The ACM Awards ceremony will also be an incredible show, and between the Party for a Cause and the awards show itself, it sounds like everyone will be there: Garth Brooks, Bryan, Lambert, McEntire, Church, Urban and lots of other talented stars were among the first ACM Awards performers announced, while Brooks & Dunn, Jackson, Brad Paisley, Lady A and -- well, there's too many to name -- were added later on. As you can see, there's plenty of overlap in performers for the Party for a Cause and the awards show.

The 2015 ACM Party for a Cause is set to take place April 17-18 at Globe Life Park in Arlington, Texas. It will feature multiple stages, interactive experiences and lip-smacking food -- and for those unable to attend, it will be taped for a two-hour CBS special, ACM Presents: Superstar Duets, which is scheduled to air on May 15. Proceeds from the event will benefit ACM Lifting Lives, the philanthropic arm of the Academy of Country Music, and military philanthropies including the Folds of Honor Foundation, Wounded Warrior Project, Navy SEAL Foundation, and Task Force Dagger Foundation.

Ticket packages to the ACM Party for a Cause are available now at Ticketmaster.com. The 50th ACM Awards will be broadcast live from AT&T Stadium in Arlington, Texas, on April 19 at 8PM ET on CBS.
