Sick New World Fest Hits Vegas and Texas in 2026 with System of a Down, Deftones, Slayer, and Korn

After hitting a bump in the road in 2025, the Sick New World festival is returning in a big way in 2026, staging massive one-day events in both Las Vegas and Forth Worth, Texas, both headlined by System of a Down.

The 2025 edition that was set to feature Metallica and Linkin Park in Las Vegas was abruptly canceled within weeks of its announcement, likely due to low ticket sales. For 2026, organizers once again tapped System of a Down, who headlined the successful first two editions of Sick New World in 2023 and 2024 in Sin City.

The 2026 Vegas edition, taking place April 25th at the Las Vegas Festival Grounds, boasts System of a Down, Korn, Bring Me the Horizon, Ministry, Evanescence, Marilyn Manson, AFI, Acid Bath, Knocked Loose, Danny Elfman, Cypress Hill, Mastodon, Underoath, Melvins, Filter, Clutch, and many more acts.

The inaugural Fort Worth edition, set for October 24th, 2026, at the Texas Motor Speedway, features System of a Down, Deftones, Slayer (celebrating the 40th anniversary of Reign in Blood), Evanescence, Ministry, AFI, Mastodon, Knocked Loose, Power Trip, The Prodigy, Underoath, Clutch, Down, Melvins, and more.

Pre-sales for both Sick New World festivals start Thursday October 23rd, at 10 a.m. local time. Sign up here for Vegas, and here for Texas.
