When was the last time they just went in a studio and recorded an album without it being LOOK WHAT WE DID ?!
One By One maybe ?!
Hasn't that been the case for almost all of the albums?
Self-Titled: Dave Grohl plays all of the instruments
The Colour and the Shape: First album recorded as a band
There Is Nothing Left to Lose: Album recorded in Dave's hometown in VA and only as a 3-piece.
One by One: Maybe that's the only one with no big gimmick
In Your Honor: Double-album: Half electric, half acoustic.
Echoes, Silence, Patience, and Grace: I don't think there is a gimmick, but mainly they experimented more with blending acoustics with the heavy stuff in the same song.
Wasting Light: Recorded in analog and in Dave's house in LA.
Sonic Highways: Recorded in eight different cities in the States
Concrete And Gold: Album produced by a pop producer.
I wasn't too impressed with Concrete and Gold. Run was very good as a lead single, but I didn't like The Sky is a Neighborhood. Honestly, I had very little desire to relisten to it in full again unlike Wasting Light, There is Nothing Left to Lose, and even Sonic Highways where I didn't feel like it's a drag listening to those albums in full.
