Funeral For A Friend head up a slew of acts confirmed for this year's Sonisphere festival.
The group will be joined by hardcore punks Gallows and British rockers Fightstar.
Speaking about their appearance, Fightstar frontman Charlie Simpson said: "Playing Sonisphere at the legendary Knebworth ground is going to be incredible! This festival has come out of nowhere to compete with the likes of Download and Reading/Leeds, so it will be an absolute must for any rock fan this summer. There are so many great bands playing over the three days and we are honoured to be part of the line-up."
Organisers have also secured the return of Skunk Anansie, pop punk group Madina Lake, Family Force 5 and Apocalyptica.
Today’s (Tuesday) confirmations join headliners Rammstein and Iron Maiden as well as Motley Crue, Slayer, Iggy And The Stooges and many more.
