Stone Temple Pilots are set to lead a bill that features Bush, Chevelle, DeftonesTheory of a Deadman, Hollywood Undead and more as part of the Monster Energy Aftershock Festival.

The just announced Monster Energy Aftershock Festival is set to go down at Sacramento's Discovery Park on September 23. The massive lineup led by STP, also boasts Escape the Fate, Otherwise, Gemini Syndrome and Oleander, in addition to the aforementioned bands. Gates for the all-day festival will open at 11 A.M. with performances beginning at noon.

The Aftershock Festival is the last scheduled date for Stone Temple Pilots' 'Core 20' tour thus far, and is set just days before the 20th anniversary of the album's release.

Chevelle and Bush will re-team after touring together in 2011, with Bush coming off of an extensive tour in support of Nickelback's latest album 'Here and Now' and Chevelle will have just finished their stint on the Carnival of Madness tour. In other words, the bands will certainly be warmed-up for this gig. The festival will also serve as a bit of a homecoming for a few acts, as Deftones and Oleander are both rooted in the Bay Area.

Tickets for the festival go on sale June 22 at 10 P.M. PT and are available for as low as $49.50 (plus fees), with V.I.P. tickets going for $99.50 (plus fees). For more info, visit the festival's official website.
