The Big Four are to be the main attraction at the Sonisphere Festival on Friday, July 8.

Metallica, Megadeth, Slayer and Anthrax will be appearing together in the UK for the first time at Kenbworth Park on the first day of the event.

Says Metallica drummer Lars Ulrich: “As soon as the Big Four gigs started rolling across Sonisphere Festivals in Eastern Europe last summer, we all felt we were part of something special. The vibe within the bands was more than anyone had anticipated and the vibe with the fans was so next level, it completely blew our minds . . . there was no way this should not happen again!!! So I am beyond psyched that the first Big Four show in Western Europe will take place on the hallowed grounds of Knebworth, where so many unique and special gigs have happened over the years”.

Megadeth’s Dave Mustaine adds:  “The Big Four concerts are the most important, most exciting event to happen in the history of live concerts in our genre, and perhaps the entire music industry. I am glad to be a part of this enormous celebration of thrash, speed, and good ole heavy metal!”.

Kerry King of Slayer is equally as excited, stating, “Now England is in line to be devastated by this heavy metal powerhouse! Can’t fucking wait!!!”

And Scott Ian of Anthrax has this to say: “Merry early Xmas present for us… more BIG FOUR shows!!! The shows we did together with our brothers in Metallica, Slayer and Megadeth were not only the high point of 2010, but also some of the best shows Anthrax have ever played. Getting to share this with our friends in the UK will be amazing”.

This historic combination completes the headlining announcements for the main stage, with Biffy Clyro topping the bill on Saturday, July 9 and Slipknot ending the festival on Sunday, July 10.
