Swedes Christian Karlsson and Linus Eklöw make up the electronic pop duo known as Galantis.
The group has over 9 million monthly listens on Spotify, and are best known for hits like "Runaway (U & I)" and "No Money".
Galantis has released two studio albums, four EPs and ten singles since their debut.
Galantis released 5 remixes of their 2018 song "Emoji" earlier this month.
Max Fees, the director of Devilpalooza, said that the deciding members took the decision into a new direction by choosing Galantis as this year's headliner.
"(Galantis) was at the top of our list," Fees said. "We wanted to give the Devilpalooza stage something that it's never seen before."
Fees said that PAB wanted to focus on making the free event inclusive to all four campuses, so that the entire student population, no matter what campus a student is based on, is able to go.
"We have a lot of attractions going on in the field," Fees said. "There's going to be food, there's going to be ... student art exhibits and we're trying to make sure that we can have all 10,000 student tickets claimed and redeemed at the Devilpalooza gates."
In past years, the event has featured games, vendors and performances by world-famous artists. Rapper T-Pain played the festival last year.
"I would love to see every Sun Devil that loves to dance to show up, full force," Fees said. "I think it's going to be a great event."
