Rushonrock rated 10/10 metallers Architects are the latest big name to join the Sonisphere bill after their latest album The Here And Now crashed the UK album charts at 57.

They hook up with Aussie crew Airbourne, NWOBHM legends Diamond Head and wacky US act Weezer on a bill already boasting the Big Four and a whole lot more!

Architects’ frontman Sam Carter said: “UK festivals are always a massive deal for us because it’s basically the biggest gathering of Architects fans we can play to.

“And this year you know it’s going to be special because the line up for Sonisphere is INSANE. It’s also a big deal because it’ll be our first UK festival since our new record came out and that record was built for festivals! We’ll see everyone at Sonisphere 2011!!!”

Heavy metal pioneers Diamond Head come to Knebworth for the biggest and most exciting show of their 35-year career. Hugely influential, to the point that it’s doubtful there would be a Big Four without them, DH’s appearance will be a special one.

When Metallica, Slayer, Megadeth and Anthrax made metal history at Sonisphere Bulgaria last summer, they chose DH’s Am I Evil to jam with all 17 members – a testimony to what a unifying force their music is. Founding member and guitarist Brian Tatler said:

“Diamond Head have been given the fantastic opportunity of opening for the Big Four at this year’s Sonisphere festival.

“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.”
