Fan-shared poster claims huge one-day Sick New World lineup
A poster circulating on r/festivals is sparking conversation: it lists System of a Down and Korn as co-headliners for Sick New World on Saturday, April 25, 2026, at the Las Vegas Festival Grounds. The artwork shows a stacked, one-day festival lineup stuffed with alt, metal and industrial names.
- System of a Down
- Korn
- Bring Me The Horizon
- Evanescence
- Marilyn Manson
- Danny Elfman
- Mastodon
- Clutch
- Knocked Loose
- Cypress Hill
- Filter
- Corrosion of Conformity
- Underoath
- Melvins
- AFI
The poster reads “Sick New World” across the top with the date and the Las Vegas Festival Grounds listed beneath. Beyond the headliners, the bill mixes legacy acts, heavier newcomers and industrial/alt staples — a lineup that reads like a one-day answer to the modern alt-metal festival.
We pulled the poster and the thread because the lineup has fans buzzing — the bill is stacked and looks like a mid-spring destination event for metal and alt-rock crowds. Keep an eye on official Sick New World channels for confirmation and ticket details; if legit, this would be one of the tighter, heavy-hitter single-day festival cards of 2026.
Extra Chill will update the wire if the festival or promoters post an official lineup or ticket announcement.
