"Nine" is the eighth studio album by American rock band Blink-182, released on September 20, 2019 through Columbia Records.
While Nine builds upon the band's collaboration with producer John Feldmann—who also produced California—it also explores outside producers and songwriters.
Much of the album's lyricism is dark in nature and was informed by world events, as well as Hoppus's battle with depression. The color wash album cover was painted by renowned graffiti artist RISK, while the album's title stems from its numerical sequence in the band's catalog. Musically, the album updates the band's pop punk sound with hip hop-inspired programming, as well as electronics.
