California’s loudest weekend is gearing up to return to Discovery Park, and Aftershock Festival 2026 is already on every rock fan’s radar. Last year’s edition set a high bar: a four-day blitz featuring headliners and heavy hitters like Korn, Blink-182, Deftones, Bring Me The Horizon, All Time Low, A Perfect Circle, Rob Zombie, and Marilyn Manson. From sunrise circle pits to arena-sized sing-alongs, 2025 turned Discovery Park into a wall-to-wall celebration of rock, alt, and metal.
The 2026 lineup and ticket details have not been announced yet—but if history is any guide, expect another multi-day, multi-stage onslaught of legends, favorites, and buzzy newcomers. Check back here for the artist lineup, single-day and 4-day passes, set times, and GA/VIP resale options as they drop. Want the best spots before they’re gone?
