THE line-up for Sonisphere has been completed after an announcement by the organisers of the Knebworth festival today (Tuesday).

Among the acts now confirmed for the three-day metal bonanza are Sonic Boom Six, The Defiled and Cerebral Ballzy.

Headliners for the Jagermeister stage have also been unveiled with The Defiled taking the stage on Friday and Black Spiders ready to bring the show to a close on Saturday.

Pete Spiby, Black Spiders frontman, said: “We’re honoured and privileged to be playing Sonisphere again this year, this time headlining the Jager stage.

“Anyone who is anyone is going to be there and when we go on stage everyone knows it’s going to be one hell of a AAA party.”

With the billing now finalised the festival, held between July 8-10 at Knebworth House, looks like it will be a winner for fans of both rock and comedy.

Thrash titans Metallica and Slayer will be joined by stand-up supremos Bill Bailey and Sean Hughes for North Herts’ biggest musical event.
