Aftershock promised its biggest lineup yet and the fan-favorite event delivered with four nonstop days at Sacramento’s Discovery Park over October 10-13. The 12th edition of the annual festival welcomed 160,000 music fans from all 50 states and 30 countries around the world, retaining its title as the West Coast’s largest rock festival and bringing an estimated $30 million economic impact to California’s capital city. With more than 130+ bands across five full stages, the Aftershock weekend hosted a number of special performances and guest appearances including Slayer’s highly-anticipated reunion set (one of just two shows from the metal legends in 2024); Slipknot who marked 25 years of their self-titled debut album, released in 1999; Iron Maiden’s two-hour performance and only 2024 U.S. festival appearance; and Mötley Crüe’s final show in a massive two-year world tour.
