After the crazy train derailment, Korn came through.

Rocklahoma festival organizers announced this week that two time Grammy-winning Korn will fill the lineup vacancy left when Ozzy Osbourne had to drop from the festival circuit.

Korn is the festival headliner on Saturday, May 25 in a night that includes In This Moment, Asking Alexandria, Tech N9ne, Beartooth and Sevendust.

The band grew from California roots and has gone on to sell nearly 40 million albums.

This isn't the first time Jonathan Davis, Brian Welch, James Shaffer, Reginald Arvizu, David Silveria and Ray Luzier have taken the stage. In fact, their bagpipe studded 2013 performance was met with rave reviews.

The festival's swift action in finding a replacement was met with appreciation by the swarm of Rocklahomans, many of whom are excited about the change.

"Awesome lineup. I'd rather have Korn than Ozzy any day! If I wanted to hear mumbling I'd go to a rap concert," one such fan commented.

Many, thug, were disappointed to hear the news that rock icon, Ozzy, would be unable to fulfill the obligation.

Festival organizers announced last week: "Regrettably, Ozzy Osbourne has postponed all of his 2019 tour dates as he recovers from an injury sustained while dealing with a recent bout of pneumonia. Osbourne fell at his Los Angeles home, aggravating years-old injuries (from his 2003 ATV accident) that required surgery last month."

Ozzy Osbourne released the following statement earlier this morning: “I can’t believe I have to reschedule more tour dates. Words cannot express how frustrated, angry and depressed I am not to be able to tour right now. I’m grateful for the love and support I’m getting from my family, my band, friends and fans, it’s really what’s keeping me going. Just know that I am getting better every day…I will fully recover…I will finish my tour…I will be back!”

Rocklahoma will take place May 24 through May 26 at Pryor Creek Music Festival Grounds in Pryor, Okla. For a look at the full lineup visit www.rocklahoma.com
