Concrete and Gold is the ninth studio album by American rock band Foo Fighters. It was produced by Greg Kurstin and released worldwide on September 15, 2017, through RCA Records. Described by the band as an album where "hard rock extremes and pop sensibilities collide", Concrete and Gold concerns the future of the United States from the viewpoint of the band's frontman and lead songwriter Dave Grohl, with the heated atmosphere of the 2016 elections and the presidency of Donald Trump cited as major influences by Grohl. Juxtapositions serve as a common motif in both the album's lyrical and musical composition, with Grohl further describing the album's overall theme as "hope and desperation".
