On the off chance you don't read the Chicago Tribune or avoided the Internet at all costs last week, well, then organizers of Lollapalooza have something very special for you: the official lineup for 2013.

Yes, on Monday (April 1), after a solid month of speculation, sources and leaks -- almost all of which turned out to be accurate -- Lolla really truly revealed the list of bands that will grace its stages, a bill topped by the Cure, Mumford & Sons, the Killers, Nine Inch Nails, Phoenix, the Postal Service, Vampire Weekend and New Order.

Rather remarkably, this marks the first time in the 20-year history of Lollapalooza that the Cure will appear at the festival, and, as any Lolla vet will surely remember, the [article id="1702562"]recently relaunched Nine Inch Nails[/article] were one of the acts that performed at the first Lollapalooza in 1991 (they also performed at Lolla in 2008). Mumford & Sons appeared in a midday slot in 2010, but this year, thanks to their [article id="1701730"]Album of the Year[/article] win at the Grammys and, you know, millions of fans -- they've been promoted to headliners.

Kendrick Lamar, Queens of the Stone Age, the Lumineers, the National, Major Lazer and Steve Aoki are also confirmed for Lollapalooza 2013, set for August 2-4 in Chicago's Grant Park.

All in all, more than 130 acts were announced on Monday, and though three-day passes have already sold out for the fest, a limited number of single-day tickets will go on sale Wednesday, April 3 at 10 a.m. CT.
