Last year, Riot Fest celebrated its 10th anniversary, and in its decade-long existence, the annual festival has expanded from its flagship Chicago event to multiple locations across the country. Now, it has solidified with its annual Denver, Chicago and Toronto installments, but as always, the Chi-Town original boasts a bigger, more impressive lineup than ever.

It’s a reunion-heavy roster, leaning on the festival’s predilection for legacy punk and rock acts. Headliners for the 2015 edition include No Doubt, System of a Down, Modest Mouse, Faith No More, the Prodigy and Iggy Pop, but even when you descend into the increasingly tiny font, you can feast your eyes on some truly standout artists. That’s why, with your best interests and sanity in mind, we have gathered the 10 acts you absolutely need to see at this year’s Riot Fest Chicago. Click through the gallery above and start planning your schedule accordingly.

Riot Fest takes place Sept. 11-13 at Chicago’s Douglas Park. Some passes are still available; get details at this location.
