Lollapalooza is pulling out all of the stops to celebrate it's 25th anniversary this July 28-31 in Chicago's Grant Park. As first reported by Consequence of Sound last week, Radiohead, Red Hot Chili Peppers, and LCD Soundsystem will headline this year. Joining the legendary rockers on the top line are J. Cole and Lana Del Ray.

Also performing this year are Ellie Goulding, Disclosure, Jane's Addiction, Future, HAIM, M83, Two Door Cinema Club, Grimes, Bloc Party, The Last Shadow Puppets, Local Natives, Foals, and many more.

For the first time in the festival's history, they have expanded the celebration to four days. While the general admission four-day passes all sold out before the lineup was released, single-day passes and VIP four-day passes went on sale this morning, March 23, at 10 a.m. The day-by-day lineup and more information can be found on Lollapalooza's website.

In a press release today, the founder and creator of the festival and Jane's Addiction frontman Perry Farrell said, "I've immersed myself in this experience for 25 years now, but it's in a constant state of evolution, living and breathing. As long as we always try to find the eye of the hurricane, the epicenter of the music that is truly connecting right now, I think we can go for another 25 years! And we'll do it by always making sure to keep it fresh. Four days this year, over 170 of the best bands, including acts from all over the world as the music community connects globally more than ever; the best sound, staging and lights. We promise the festival will always strive to be the 'lifeblood' of the music scene."
