Ozzy Osbourne: “Last year's show with Black Sabbath was just incredible and I'm thrilled to be coming back this year with Zakk, Tommy, Blasko and Adam to headline the 21st anniversary of Ozzfest."

Slipknot’s Clown: "It's that incredible time again where Ozzfest and Knotfest meet up to bring all music fans together for two days of rock and roll. Let's not forget the beautiful culture we are involved in and the history that is being written. Join the true passion of our concepts. I'll see you there. Stay (sic)."

Sharon Osbourne: "Ozzfest Meets Knotfest is coming back for another round. Last year we had over 75,000 people attend and we have another great lineup this year with Ozzy's first solo show in L.A. in more than six years. This is not just another show... it's Ozzfest Meets Knotfest! And this year's event means the world to me as we'll be amongst friends like Prophets Of Rage, Rob Zombie, Deftones, Marilyn Manson and Stone Sour... it's going to be another amazing weekend."

Corey Taylor (Slipknot/Stone Sour): "Knotfest was never supposed to be exclusively about Slipknot. It was always about the things that fueled the spirit of Slipknot: music, art, passion, insanity, and the tribes that give it power. So it would make sense for Knotfest to carry on these ideas, even without Slipknot. Because these things are the gasoline of creativity, and there's plenty to go around, with plenty of great bands, acts and things to see. Teaming up again with Ozzfest means another weekend of the biggest, baddest, loudest and best. I hope you all will join us; it's going to be (sic)."
