10 Rock Collaborations That Made Absolutely No Sense

Most fans who are engrained in the sound of the Foo Fighters typically know what they are getting. From the loud guitars that populate every single track to the heady introspective moments that pop up every now and again, Dave Grohl's tried and true approach to rock music has a few more common patterns revealing themselves as the years go on. With Sonic Highways though, they still had a few right turns up their sleeve on Congregation.

Looking to go to different studios around the country and record a song in them, this was the product of going into Nashville, Tennessee, which is almost palpable when listening to the shimmery guitars on display here. As much as that could have been the country flair starting up, the real shock comes in the back half when you hear a sort of classical solo brought into the mix.

At first, this kind of thing feels like it fits in the wheelhouse of Chris Shiftlett, until you see the video and realize that it is country superstar Zac Brown behind the fretboard. Aside from his jam band style, Brown was always a bit of a monster behind the fretboard, and this understated take on more classical pieces is a welcome switch up where the Foos would have just put a regular solo. Though Sonic Highways doesn't hold up as coherent as it could have been, this was a good example of when that experimental side worked.
