Before Sunday's ACM Awards, Florida Georgia Line and six fellow Big Machine Label Group artists spent their Friday night (April 4) helping fight hunger in America.

The duo took the stage, along with Rascal Flatts, Thomas Rhett, Justin Moore, the Cadillac Three, Cassadee Pope and Danielle Bradbery, at Outnumber Hunger Live! at the ACM Party for a Cause Festival.

Held at the LINQ in Las Vegas, the event benefited Outnumber Hunger, a collaboration between General Mills, Big Machine Label Group and Feeding America that supports the U.S.'s local food banks. The campaign has helped secure more than 25 million meals since March 2011, and concert attendees helped grow that number through on-site activities.
