Aftershock Festival is a hard rock and metal music festival in Sacramento, California. Started in 2012, the festival is part of the Danny Wimmer Presents family, alongside other fan favorites such as Welcome To Rockville, Louder Than Life, and more. Anchored in hard rock and metal, Aftershock annually puts together a stacked lineup of acts representing the wide range of sounds within the rock umbrella. Adding an extra day last year after having to take 2020 off like everyone else, the festival is four days of rock and roll bliss at the scenic Discovery Park.
