Riot Fest has announced additions to their 2021 edition after Sunday headliners Nine Inch Nails cancelled all of their 2021 shows due to COVID. Slipknot will now close out the festival's Sunday night on Sunday, September 19.

In addition, those who purchased three-day or single-day Sunday passes, as well as 2020 ticketholders who held onto their passes until this year, will receive access to a pre-show on Thursday, September 16. Morrissey will headline, and he'll curate the day's lineup, which is still to be announced. Tickets for Thursday will also go on sale today (8/19) at 12 PM CST, and proceeds will benefit the Chicago Coalition for the Homeless, plus other charities, still to be announced.

"I got so excited putting together this Thursday lineup… we’ve never done anything like this before," festival founder Michael Petryshyn said in a statement. "So we wanted to open the gates to everyone in a fair way, while still respecting our loyal fans who received free Thursday passes for keeping their tickets through thick and thin. Giving Thursday’s ticket proceeds back to our Chicago community feels like the perfect win-win scenario. It makes our Thursday Preview Party feel extra special: it’s now a gift to our whole community, whether you’re there or not."

With Morrissey's reputation for cancelling shows, as well as the unfortunately things he's been opening his bigmouth to say, quite often, over the last few years, he's an interesting choice for Thursday headliner. Stay tuned, and see the updated lineup below, along with pictures from 2019.
