As it appears, Dave Grohl and the Foo Fighters are in the process of recording their follow up to 2011’s Wasting Light by recording in various locations. They’ve been spotted in Nashville, Chicago, Joshua Tree, CA and more at different studios. Dave Grohl promised that the band would do something no one has ever done, and this appears to be it.

Thanks to social media, their cover has been blown on several occasions as you’ll see below. However they’ve also been keeping fans updated on the recording process with a series of Facebook posts.

Yes, those are 3D glasses….

As for official word, we’ll have to wait on that, but it appears the Foos are prepping the release of something huge that comes with 3D glasses. Stay tuned.
