Riot Fest, the three-day music festival in Chicago, announces its 2026 lineup. Multiple outlets report that the festival will run September 18–20 and that the bill includes major headliners and additional artists. The lineup highlights include Tool, Morrissey, Alanis Morissette, Iggy Pop, and Afroman, all listed among the confirmed acts. Newsweek and Consequence of Sound both describe the announcement as an official release of the festival’s program for 2026, pointing readers to the newly published lineup details. While the sources emphasize the featured headlining names above, they agree on the core event information: Riot Fest’s Chicago location, the three-day dates in September, and the presence of those specific performers in the 2026 lineup. The articles do not provide further detail beyond the lineup highlights and scheduling in the material reviewed, and they do not present conflicting claims about the dates or the performers named. Riot Fest is therefore positioned as returning with a 2026 edition built around a mix of rock, alternative, and hip-hop-leaning acts.
