More bands have been announced for the UK edition of Sonisphere, including some cracking Terrorizer-friendly bands to add to the already stellar bill of The Big effing 4!!!!, Watain, Black Dahlia Murder and our favourites comics Bill Bailey and Andrew O'Neill.

The legendary brothers from Brazil, Cavalera Conspiracy, join the gang, with Max stating that: "I'm fucking super excited to be part of the Sonisphere Festival in the UK with Cavalera Conspiracy.  We have a new album out, Blunt Force Trauma, and me and Iggor are on fire.  We are gonna play stuff from the first CD, Inflikted, new stuff, some Sepultura and Nailbomb classics, so it should be a storm of metal coming to Sonisphere UK. I can't wait!"

Reading thrashers Sylosis also take the Apollo stage telling all: "We are beyond thrilled to be back at Sonisphere again this year. To be on the main stage is an absolute dream come true for all of us and will be our biggest show to date. Knowing that we will be the first band on that stage after Metallica the night before kind of blows my mind. It's an honour to play on the same stage as so many influential bands."

On the Saturn stage, America’s loudest lounge singer Richard Cheese will perform swingin’ Vegas versions of rock, rap, and metal hits, “swankifying” contemporary songs into traditional pop vocal standards. The perfect mix of music, martini, and madcap.

Joining them will be Canadian hardcore heroes Cancer Bats, pop punkers Bad Religion, our coverstars Kylesa and the almighty Paradise Lost.

“It’s really great to be added to the Sonisphere bill,” agrees PL frontman Nick Holmes. “It’s a top line up this year and I intended to go along anyway, only now I don’t have to blag my way in! Look forward to seeing you all there for a monster weekend of metal!”

That's not all, The Red Bull Bedroom Jam stage returns and has promised appearances from Djent heroes Tesseract and noisemongers Rolo Tomassi. Tesseract say; “Sonisphere is without a doubt one of the coolest festivals on the planet, and this year's lineup looks incredible. We feel privileged to be representing the new sound emerging on the scene and be playing the same festival alongside the legends.”

Plus Indian metallers Demonic Ressurection make their way onto the Jagermeister stage, saying; "We are at a loss for words to describe how we feel confirming to play Sonisphere, just the thought of watching the Big 4 let alone be playing the same festival as them is enough to give us goosebumps. Not to mention the insane lineup of bands like Opeth (who we've opened for in India), Arch Enemy, Periphery and many others who we can't wait to see. DR fans can expect a blistering performance from us, it is our first gig in the UK and we intend to make it a memorable one." Orange Goblin have also been added. Frontman Ben Ward (who was recently spotted guesting with Kyuss Lives at their recent London Shows) reckons: “Orange Goblin are delighted and honoured to be a part of Sonisphere 2011. This festival marks the first ever ‘Big 4’ shows on British soil so the weekend will go down in the annuls of metal history! Although, now Orange Goblin are playing I guess it should be re-named the Big 5!!!”
