The organizers of the Aftershock Festival shared a teaser video on the event’s Facebook page, and if you listen to it carefully, you will find a potential clue as to the headliner might be. During the cryptic video, you hear distorted snippets of System of a Down’s classic track “Prison Song.” We can only guess that this mean’ the group will be one of the headliners for the festival, which will take place on October 13th and 14th at Discovery Park in Sacramento, CA. We will know if this rumor is true when the announcement is made on April 9th. [UPDATE: yeah, they’re doing it]
