UPDATE: The full lineup is set for Morgan Wallen's Sand in My Boots festival, which will be headlined by Post Malone, Brooks & Dunn and HARDY.

Rounding out the bill is a highly eclectic list of rock, country, dance and hip-hop acts, including Diplo, Riley Green, Chase Rice, ERNEST, T-Pain, Wiz Khalifa, 2 Chainz, Three 6 Mafia, Moneybagg Yo, The War on Drugs, 3 Doors Down, Future Islands, Real Estate and Wild Nothing.

Wallen just wrapped his massive One Night At a Time Tour, which drew 3.11m fans across 87 shows, 51 of them in stadiums.

Morgan Wallen will set up shop on the site of the Hangout Festival in Gulf Shores, Alabama, next spring for his first dedicated festival, Sand in My Boots, in tandem with AEG Presents/Goldenvoice.

The 5/16-18 event appears to be taking the place of the annual Hangout, which is ordinarily held over the same weekend. It will comprise a to-be-announced, "highly curated multigenre lineup with some of Wallen’s closest friends, favorite artists, those who have inspired him and those he has always wanted to perform with."

"Creating a festival with Morgan has been a dream come true and some of the most fun I've ever had booking a show," said Goldenvoice EVP Stacy Vee, who's hosted Wallen twice at the company's Stagecoach. "I can’t wait for fans to come and experience one of the most eclectic and electric lineups and on-site experiences the world has ever seen.”

Added AEG's Reeves Price, who produces Hangout, "The opportunity to bring Morgan’s world to life on the beach in Gulf Shores is something very special. The fact that it coincides with the 15th anniversary of the Hangout Festival only makes it more special. We can’t wait to see everyone back on the beach in May.”
