Weezer, Airbourne and more for Sonisphere

Sonisphere welcomes Weezer's only UK festival appearance this summer, Architects' first festival appearance in this country, Airbourne's glorious return after scaling the Saturn Stage scaffholding in 2009 and the biggest show to date by one of the Big Four's main influences - the legendary Diamond Head.

When METALLICA, SLAYER, MEGADETH and ANTHRAX made metal history at SONISPHERE BULGARIA last year summer, they chose DIAMOND HEAD’s “Am I Evil” to jam with all seventeen members, a testament to what a unifying force their music is. Founding member and guitarist Brian Tatler says of the upcoming appearance:

"Diamond Head have been given the fantastic opportunity of opening for the BIG 4 at this years Sonisphere festival, Knebworth Friday 8th July. This will be Diamond Head's biggest ever show and myself and the other band members are very excited and looking forward to what will be an historic event. Knebworth is one of those venues you only dream of playing. I saw Led Zeppelin there in 1979 and never imagined that one day I would be on that stage, it proves the saying 'anything is possible'! It also means I get to see my friends in Metallica and Megadeth once again which is always fun; I owe both Lars Ulrich and Dave Mustaine a beer.”

The Big FourMetallica, Megadeth, Slayer and AnthraxSlipknot and Biffy Clyro will headline this year's festival. Motorhead, In Flames, Parkway Drive and Mastodon are also on the bill, with many more artists still to be announcedS
