[img=071011_sonisphere.png]NME.com recently interviewed Sonisphere organizer Stuart Galbraith about the line-up for their 2012 festival. Galbraith mentions that they are in "talks" to get The Foo Fighters and Red Hot Chili Peppers on the bill, and he mentions Green Day as well.

[quote]Asked if he would consider booking either Foo Fighters or Red Hot Chili Peppers for 2012, he said: 'They're both two that we're talking to, amongst a whole list of others. I also think we could have Green Day and Blink-182 here, but none of those are confirmed.'[/quote]
Obviously, this is just a rumor at the moment and should be taken with a grain of salt. But it's nice to see some festivals would like Green Day on their bill, even though they haven't put out new material since 2009.

We'll be sure to post an update if there is one in the future.
