What is the Foo Fighters' 2014 concept album recorded in multiple cities?

Foo Fighters’ 2014 concept album recorded in multiple cities was Sonic Highways.

Sonic Highways is the band’s eighth studio album, released on November 10, 2014. Dave Grohl designed it as a musical journey through American recording history: the band traveled to eight cities, interviewed local musicians and music-industry figures, and recorded one song in each location.

The cities included Chicago, Washington, D.C., Nashville, Austin, Los Angeles, New Orleans, Seattle, and New York City. Each song reflects the musical character and stories of its recording location, with guest contributions from artists connected to those scenes. The project was produced by Foo Fighters and Butch Vig, who had also produced Wasting Light.

The album was developed alongside the HBO documentary series Foo Fighters: Sonic Highways. That series follows Grohl’s interviews and the band’s recording process, making the album more than a conventional collection of songs. It is sometimes confused with Wasting Light because both albums were produced by Butch Vig, but Wasting Light was recorded primarily at Grohl’s garage in California.
