With festival season fast-approaching, the lineups are starting to roll in. Chicago's Spring Awakening has just released the lineup for their third-annual event. From June 12-14, over 75 artists will perform across the festival's four stages at Soldier Field.

The 2015 headliners include Zedd, Hardwell, Tiesto, Diplo, Eric Prydz and Afrojack, with a special headliner to be announced. If the track used in the lineup announcement video above is any indication, maybe that unannounced headliner will be a set from Jack U. For now, we'll have to wait and see.

*EDIT: It has been confirmed that the unannounced headliner is in fact Jack U. Bam!

Also featured on the lineup are heavyweights such as Dada Life, Flosstradamus, Duke Dumont, Martin Garrix, Excision and Zeds Dead. With many festival lineups still to be announced, this React Presents event is setting the bar high.

After expanding to three days in 2013, Spring Awakening is continuing its expansion, now adding a fourth stage to the festival grounds. Aside from the main stage, trance legend Paul Van Dyk headlines the Trance Arena, with dubstep producer Zomboy taking over the Bass Kitchen stage, and Hot Creations Records own Jamie Jones headlining the Beatport Stage. With these varying stages, dance music fans of all kinds will have something to enjoy at Spring Awakening.

Spring Awakening is a 18+ event. After-parties for the event will be announced two weeks prior to the festival. With a heavy-hitting lineup like this, you can expect there to be some all-star caliber late night events following each day's conclusion.
