System Of A Down, Korn, Deftones and Slayer will headline the 2026 edition of Sick New World, with the festival returning to Las Vegas and adding a second location in Fort Worth, Texas.

The Las Vegas event will take place May 16 at the Las Vegas Festival Grounds, while the inaugural Fort Worth show is scheduled for May 23 at Panther Island Pavilion. Both events will feature the same lineup of bands.

System Of A Down will perform at Sick New World for the first time since the festival launched in 2023. The band joins returning headliners Korn and Deftones, who have both appeared at previous editions of the event.

Slayer’s inclusion marks another high-profile reunion for the thrash metal pioneers, who ended their farewell tour in 2019. The band announced their comeback earlier this year with select festival appearances planned for 2025 and 2026.

Organizers have not yet announced the complete lineup or ticket sale dates for either location. The festival has previously featured acts including Pantera, Linkin Park, and Incubus during its three-year run in Las Vegas.

The expansion to Fort Worth represents the first time Sick New World has scheduled events outside Nevada. Panther Island Pavilion, which will host the Texas date, has a capacity of approximately 20,000 for outdoor concerts.
