Lollapalooza 2014 Lineup Revealed: Eminem And More Coming To Chicago

OutKast, Skrillex also top the bill for Lolla 2014, set for August 1-3.

Well, so much for secrecy.

Confirming earlier reports, Eminem, OutKast, Kings Of Leon and Skrillex have been announced as headliners for for Lollapalooza 2014, set for August 1-3 in Chicago's Grant Park.

Arctic Monkeys, Calvin Harris, Lorde, the Avett Brothers, Foster The People, Childish Gambino and Nas are just some of the other 130 artists confirmed for this year's Lolla, which is marking a decade in the iconic Chicago park.

Want even more names? Okay, how about Broken Bells, Spoon, Young The Giant, Phantogram and Chicago's very own Chance the Rapper. And, as in previous years, Lollapalooza co-founder Perry Farrell will host some of dance music's biggest names — including Zedd, Sebastian Ingrosso and Flosstradamus — on his own namesake stage.

Up-and-coming artists like Bleachers, NONONO and Vic Mensa are also on the bill, as are a spate of international acts, including South African rock act Kongos and Ireland's Kodaline.

Eminem previously headlined Lollapalooza in 2011, and KOL did the same in 2009. Skrillex follows in the footsteps of dance acts like Avicii and Justice, who made the leap to the main stages in 2012.
