Lollaplooza's come a long way since its days as a showcase for Jane's Addiction and the band's alt brethren. It's now a venerable summer staple in Chicago's Grant Park that attracts music lovers from all around the world. To celebrate how far this great American music festival has come in its 25 years rocking millions of diehard fans, Lollapalooza just unveiled a whopper of a lineup for 2016.

Radiohead (who are certainly making the rounds this festival season already), LCD Soundsystem, and the Red Hot Chili Peppers are set to headline each day of the festival, as well as additional big names like Lana del Rey and J. Cole. In fact, there are so many artists interested in playing Lolla this year that, for the first time, the festival is expanding to a four-day format, stretching its dates from July 28 – 31.

Both Radiohead and RHCP have headlined the festival before and both have new albums in the works, which likely means new tunes to reward all the fans braving the heat to see their heroes; LCD Soundsystem, whose planned reunion tour also includes performances at Coachella, Bonnaroo , and perhaps Outside Lands , has also promised new music.

No full lineup poster yet, but tickets go on sale March 22, 2016. With planned headliners this big, you'll want to grab your Lolla spot as soon as you can.
