This is Lollapalooza’s 25th year of existence, and the festival is going big to celebrate its silver jubilee. There have been rumors floating around for a while, but now it’s confirmed: Radiohead, Red Hot Chili Peppers and LCD Soundsystem are all headlining, and Lana Del Rey and J. Cole are also set to perform, Billboard reports. The fest is expanding from its usual three days to four this year, and the whole thing is going down 7/28-31 at Chicago’s Grant Park. The rest of the official lineup is expected to arrive this Tuesday, 3/22, which is when tickets go on sale.
