Lollapalooza 2013 Official Lineup Announcement: The Cure, NIN And More To Play Grant Park Aug. 2-4

Lollapalooza officials have finally released the official word: The Cure, Nine Inch Nails, Mumford & Sons and New Order are among the headliners for the 2013 music festival in Chicago's Grant Park on Aug. 4-6.

The somewhat anticlimactic Monday announcement ends months of speculation which, in recent days, had ramped up intensely amid leaks, rumors and credible industry confirmations.

Though organizers didn't specify a reason for changing their widely-reported announcement date or acknowledge any of the reported leaks, the lineup reveal was bumped from April 9 to April 1.

Other acts include a reunion of The Postal Service, The Lumineers, Kendrick Lamar, Phoenix, Vampire Weekend and Chicago rockers the Smith Westerns (who last played the festival in 2011). In all, the three-day festival will feature more than 100 bands, welcome an estimated 300,000 fest-goers and hopefully several thousand more ridiculously-priced-yet-totally-delicious lobster corndogs.

Also among the lineup are other locals including Wild Belle, Yawn, Chance The Rapper and Supreme Cuts. The synth-pop duo behind the anthem of SXSW, Icona Pop, is also set to play the festival. And, yes, Lolla will most certainly have a "Harlem Shake" moment.

With the lineup officially unveiled, single-day passes will go on sale Wednesday. Three-day passes, Early Bird discount and "secret sale" souvenir passes have already sold out, some within minutes of becoming available.

According to the Chicago Tribune's Greg Kot, it took less than three hours for Lollapalooza to sell out of its 80,000 $235 three-day passes last week, so the single-day passes, at $95 apiece, are also anticipated to go fast.
