October 1–2026 (day: 4) · Sacramento, California, USA · Discovery Park
Aftershock is California's largest rock and metal festival, held annually at Discovery Park in Sacramento. The four-day event features a massive lineup of legendary rock and metal bands alongside rising stars across multiple stages. Known as a 'pilgrimage' for rock devotees, it offers a high-energy atmosphere with gourmet food, craft beer, and unique art activations. For the 2026 edition, the festival is introducing onsite camping options at Cal Expo with shuttle service for the first time.
Aftershock partners with Clean Vibes, an organization focused on cleaning up and recycling waste at music festivals. Volunteers can work in exchange for a festival pass to help keep the park clean. The festival also has a "Farm to Fork" initiative that highlights sustainable agriculture and local food purveyors.
