Foo Fighters have announced that their upcoming record will be a double CD release with each disc representing a different sound for the band. This, their fifth studio album will include a rock disc and a more sensitive, acoustic disc.
Grohl had this to say to Billboard:
The good thing about doing it is that you split it up so that there's no middle ground. So the rock stuff is the most rocking stuff we've ever worked on, ever and the acoustic stuff will be the trippiest, most beautiful, sleepy music we've ever made, almost like a soundtrack.
While the release date has yet to be announced, the set is expected this summer. The band released their last record, One By One in 2002.
