Lollapalooza‘s 20th birthday party is still six months off, but we now know a few acts who will partake in the festivities. Eminem, Foo Fighters, and Muse will be among the six acts to headline this year’s edition, reports The Chicago Tribune‘s Greg Kot.

Set to take place from August 5-7th in Chicago’s Grant Park, the festival will reportedly also feature the likes of Best Coast, Girl Talk, Crystal Castles, and Lykke Li.

An official line-up announcement is not expected until April.
