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.
