The festival is set to feature 60 bands from the old-school emo and pop-punk genre, much to the delight of fans who feel the line up will take them back to their teen years.
Among the headliners include legendary bands like Paramore, My Chemical Romance and Jimmy Eat World.
Fans across the UK have been posting about the event, gutted that it is being held in America and dreaming of ways they might be able to get there.
But with 60 artists set to feature in just one day, there are also fears that it may end up like the disastrous Fyre Festival in 2017.
Here is everything you need to know about the festival – including who is on the line up and how to get tickets.

Who are Sheffield band Bring Me The Horizon?
Frontman Oli Sykes and his bandmates originally hail from the Steel City, attending Stocksbridge High School in their youth.
The metal rockband have had numerous sounds and influences over the years, from screamo to more mellow rock in recent years.
Although their first album, Count Your Blessings, was classed as ‘deathcore’, their more recent albums have also featured new genres, including electronica and pop.
Last year, Oli told The Sun that fellow Sheffield band Arctic Monkeys had been a ‘massive inspiration’ for Bring Me The Horizon and that he would love to collaborate with the band at some point.
Both bands are headlining Leeds Festival this year.
