Aftershock returns as Northern California’s loudest fest and the largest hard rock festival on the West Coast with four full days of music in Sacramento’s Discovery Park Oct. 6 to 9. While the bill is heavy on rock, Aftershock boasts an eclectic range of headliners in Slipknot, KISS, My Chemical Romance and Muse.

It’ll will be followed the following week by the inaugural country music GoldenSky Festival, also presented by promoter Danny Wimmer Presents. DWP will keep some of its infrastructure in place for the event, headlined by Tim McGraw and Sam Hunt. Tickets for Aftershock are available online.

Unlike BottleRock Napa and Outside Lands, which entices attendees with culinary and drink offerings, Aftershock has always emphasized the music, with two main stages and two side stages. There are, however, a handful of beer, spirits, wine and cannabis vendors.

Aftershock has seen consistent growth from its 2012 inception, when Stone Temple Pilots headlined the inaugural one-day event. The event has been at Discovery Park every year, save one, when it was moved to the nearby Gibson Ranch.

Northern California is an infrequent stop for hard rock acts, and Aftershock is the lone festival here specifically targeting fans of heavy bands and artists.

Toyota Pavilion at Concord (formerly known as Concord Pavilion) is an amphitheatre located in Concord, California. It is owned by the City of Concord and operated by Live Nation. The Pavilion has a capacity of 12,500 people and opened in 1975 as the Concord Pavilion. It is used for concerts, local community events (including an annual jazz festival) and local high school graduations. The Pavilion was designed by architect Frank Gehry and landscape architect Peter Walker. Gehry also designed its 1996 renovation and expansion, which included more parking and seats. The venue has hosted numerous professional musical acts over the years of its operation and continues to do so to this day.
