Well, so much for secrecy.
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.
Three-day passes for this year's fest went on sale Monday — and promptly sold out within an hour. Single-day passes and various VIP packages will be available at 11 am ET (10 am CT) through Lollapalooza.com.
