Annual Discovery Park event returns Oct. 1–4 with massive slate of rock, punk and metal acts
SACRAMENTO — Northern California’s biggest rock festival is preparing to shake the capital city again this fall as organizers have officially unveiled the full lineup for the 2026 Aftershock Festival, a four-day celebration of rock, punk and heavy metal returning to Sacramento’s Discovery Park.
The annual festival, widely regarded as the largest rock and metal music event on the West Coast, will take place Oct. 1 through Oct. 4, transforming the riverside park into a massive outdoor concert venue featuring dozens of bands across multiple stages.
Produced by Danny Wimmer Presents, Aftershock has grown dramatically since launching in Sacramento in 2012. The event now draws tens of thousands of fans from across the country and routinely features more than 100 bands over four days of performances.
The 2026 lineup continues that tradition with a diverse mix of legendary rock acts, modern heavy bands, reunion performances and anniversary sets spanning the full spectrum of the rock and metal scene.
Among the top names announced for the festival are Turnstile, Gojira, Marilyn Manson, Knocked Loose, Three Days Grace with Adam Gontier, Lamb of God and Dream Theater, the latter performing a special set celebrating the band’s 40th anniversary.
Also appearing are influential post-hardcore and alternative rock favorites Taking Back Sunday, Alkaline Trio, Story of the Year and Bowling for Soup, along with hard-hitting metal standouts such as Trivium, Powerwolf, Slaughter to Prevail and August Burns Red.
Fans can also expect a number of special performances and reunion appearances that have become a hallmark of the festival. The Dillinger Escape Plan will perform a West Coast reunion show, while Chiodos and Get Scared are also slated for reunion appearances. Flyleaf will reunite with original vocalist Lacey Sturm for a special performance, and Crossfade will return to the West Coast stage.
Additional acts on the 2026 lineup include Hollywood Undead, In This Moment, Black Veil Brides, Kerry King, Machine Head, Power Trip, Testament, Basement, Chimaira, State Champs, Hoobastank, Hinder, Static-X, Hatebreed, Imminence, GWAR, Carcass, DragonForce, Alestorm, Death Angel, Sunami, Mom Jeans and All Shall Perish, among many others scheduled across the four-day event.
Several performers will bring unique sets to Sacramento as part of milestone celebrations. Thrash metal pioneers Exodus will commemorate 40 years of their landmark album Bonded by Blood, while GWAR is planning a special 40th-anniversary performance. Cavalera will perform Sepultura’s classic Chaos A.D. album in full during the festival.
Discovery Park, located at 1000 Garden Highway near the confluence of the Sacramento and American rivers, once again serves as the festival’s home base. The sprawling venue allows organizers to construct multiple stages, vendor villages, art installations and food areas throughout the park’s riverfront setting.
Festival gates typically open late morning each day, with music running throughout the afternoon and evening as fans move between stages to catch their favorite acts.
In addition to the music, Aftershock has evolved into a destination experience featuring food vendors, craft beverages, interactive exhibits and merchandise areas. Shuttle services are also provided from Cal Expo to help move large crowds to and from the venue.
The event’s continued growth has had a notable economic impact on the region as well. Local hotels, restaurants and businesses see a major boost during the festival weekend as thousands of visitors travel to Sacramento for the event.
Passes for the 2026 festival are currently available through the official Aftershock website, with options including four-day general admission, single-day passes and VIP experiences.
