AMERICAN industrial rockers Fear Factory have been added to the Sonisphere Festival line-up at Knebworth House.

Two decades after the death metal group first formed, founder member and guitarist Dino Cazares and Burton C Bell have put aside their differences to reform and play the Knebworth rock event on August 1-2.

Vocalist Burton told Metal Hammer: "We're going to let the music speak for itself and come out there and when we play Sonisphere, we're going to bust out our best classics.

"By then we'll have some new songs to introduce to some fans."

The two-day Sonisphere camping extravaganza will be headlined by nu-metal favourites Linkin Park and rock giants Metallica, who will play a full two-hour set to close the festival.

Others on the Knebworth bill include American industrial rockers Nine Inch Nails, Welsh bands Bullet For My Valentine and Feeder, Irish legends Thin Lizzy, grunge gods Alice In Chains and American rock group Taking Back Sunday.
