Hangout Music Festival has revealed its 2017 lineup, headlined by Mumford & Sons, Twenty One Pilots, Chance the Rapper, and Frank Ocean. The festival takes place May 19th – 21st, 2017 in Gulf Shores, Alabama.

Notable undercard acts include MGMT, Sigur Ros, Weezer, Major Lazer, A$AP Ferg, Charli XCX, Franz Ferdinand, and Mac DeMarco, among others.

Notably, headliner Frank Ocean is set to make his first live appearance since 2014. Ocean announced a string of summer tour dates in support of recently released albums Endless and Blonde earlier today. He will also play Danish festival NorthSide, British festival Lovebox, and American festivals Sasquatch! Music Festival and Panorama Music Festival.

UPDATE (5/11): According to Brooklyn Vegan, Frank Ocean has dropped out of his headlining slot at Hangout Music Festival. He will be replaced by Phoenix. A short while back, he dropped out of a prominent spot at Sasquatch Festival in the Pacific Northwest (he was replaced with LCD Soundsystem at that festival).

.@wearephoenix Due to production delays beyond his control Frank Ocean will be unable to perform. He passes on his apologies & hopes to return to AL soon.
