Sonic Highways is the eighth studio album by the American rock band Foo Fighters. It was produced by Butch Vig and was released on November 10, 2014, on RCA Records. In writing the album's eight songs, singer and guitarist Dave Grohl traveled to eight cities across the United States to conduct interviews with musicians, recording engineers, record producers, and other individuals discussing each city's musical history, which he used as inspiration for the songs' lyrics. The band and Vig then traveled to a different recording location in each city to record the songs. Each track features contributions from one or more musicians with ties to that city's musical history. The process was filmed for a companion television series, Foo Fighters: Sonic Highways, which was broadcast on HBO in the months surrounding the album's release.
Despite initially announcing a break after supporting Wasting Light, Grohl later stated in January 2013 that the band had started writing material for an eighth studio album. On February 20, 2013, at the Brit Awards, Grohl said he was flying back to America the following day to start work on the next album. In an August 2013 interview with XFM, Grohl announced that their next album was slated for a 2014 release, saying:
According to lead guitarist Chris Shiflett, Grohl would finish the lyrics just before recording his vocals, the last part of each song. This time the compositions would drift away from "love letters and confused relationships" to deal with the feelings Grohl had regarding each city during production.
