The 2016 ACM Awards in Las Vegas will once again expand to include a multi-day festival loaded with performances from country's biggest stars. Carrie Underwood, Dierks Bentley and Kenny Chesney will headline the fourth annual ACM Party for a Cause Festival, April 1-3, but nearly two dozen others have been added.

The three-day festival will also include performances from Frankie Ballard, Sam Hunt, Chris Stapleton, Chris Young and about 20 other known country hitmakers. Lee Brice, Maddie & Tae, Dustin Lynch and Kelsea Ballerini are a few others set to perform. Tickets for the three-day festival are on sale now through Ticketmaster, with proceeds benefiting the ACM's charitable arm, ACM Lifting Lives. Over $400,000 has been donated to military organizations after the first three ACM Party for a Cause festivals.

Fans can expect multiple stages, interactive games, a country marketplace and more during this party at the Las Vegas Festival Grounds on the Las Vegas Strip. The 2016 ACM Awards air April 3 at 8PM ET on CBS. Bentley will join Luke Bryan to host next year. It's Bryan's third year hosting, and his first as the senior co-host. Bentley will host the show for the first time, replacing longtime host Blake Shelton who stepped away after five years.

Nominations and a list of performers and presenters for the 2016 ACM Awards will come this winter and spring. A full daily schedule for the festival will also be announced closer to the festival. Kip Moore, Kellie Pickler, Lauren Alaina, Granger Smith and Brothers Osborne are a few others set to perform. There is also going to be an ACM Women of Country night hosted by Underwood.
