With lineup announcements from other marquee festivals like Coachella and Bonnaroo, anticipation has been building for this summer's festival season. However, news has so far been scarce about Chicago's Lollapalooza, despite the fact that tickets go on sale next Tuesday.

Although the lineup is not set to be officially announced until next week, the Chicago Tribune's Greg Kot reports via industry sources that the headliners will include Eminem, Skrillex, Kings of Leon and The Arctic Monkeys.

All four acts have played Lollapalooza before. Eminem last headlined the festival in 2011, while Kings of Leon headlined in 2009. Skrillex and Arctic Monkeys have played prominent sets at the festival in the past, but this will be both acts' first time headlining.

According to the Chicago Tribune, Lollapalooza sold out last year with 300,000 visitors. This year also marks the 10th year the festival has been a stationary event in Chicago. It started out as a touring festival in 1991. 

The full lineup will be officially announced next week.
