1989 is the fifth studio album by the American singer-songwriter Taylor Swift. It was released on October 27, 2014, through Big Machine Records. Titled after Swift's birth year as a symbolic rebirth, the album recalibrated her artistic identity from country music to pop. Swift produced 1989 with Max Martin, Shellback, Jack Antonoff, Ryan Tedder, Nathan Chapman, and Imogen Heap. Its 1980s-inspired synth-pop production incorporates dense synthesizers, programmed drum machines, and processed electronic backing vocals, abandoning the acoustic arrangements that had characterized Swift's past albums. The songs chronicle the aftermath of a failed relationship with lyrics that expand on Swift's autobiographical details; they depict heartbreak, recovery, and self-discovery from lighthearted, wistful, and nostalgic perspectives. 1989 was promoted with the 1989 World Tour, the highest-grossing concert tour of 2015. Its seven singles included the US Billboard Hot 100 number-ones "Shake It Off", "Blank Space", and "Bad Blood", and the top-ten entries "Style" and "Wildest Dreams".
