Earlier in the day on Saturday (November 30), the crowd destroyed a security barricade beyond repair during a set from Behemoth, causing the festival organizers to cancel all remaining performances after several failed attempts to fix the barricade. The crowd then allegedly became hostile at the venue.
Shown in the tweet below is reportedly Evanescence's gear engulfed in a massive blaze with irate concertgoers looking on, with some even further stoking the fire.
Watch that footage below.
Slipknot have issued a statement on Facebook following the incident:
Safety — especially the safety of our fans and fellow bands — is priority number one. We apologize profusely and hope you all understand. If anything were to happen to any of you, we wouldn't forgive ourselves. Also, If we could have fixed the barricade correctly, we would have gone on stage. Again, we hope you all understand and we will try to make it up to you as soon as we can.
Meanwhile, Evanescence have issued a statement of their own.
"We are heartbroken we didn't get to play for you tonight, México City," reads a post from the band's Instagram account. "Your safety, your life is more important than any show! We love you and we will be back soon, that's a promise."
So far, the performance has not been rescheduled.
Find the both of the bands' responses below.
Due to unforeseen circumstances, Slipknot were not able to perform at last night's Knotfest. . Security barricades became an issue, and it was decided that for the safety of the fans, neither Slipknot or special guests Evanescence could take the stage. . We had hoped to be able to perform today, but regrettably, a situation arose onstage after the cancellation that damaged or destroyed gear that would have been necessary to play. . We are extremely disappointed that we did not get the chance to perform, but the safety of our fans and our community is our biggest priority. We will look to get back to Mexico sometime in the future. . Slipknot
