Prism (stylized as PRISM) is the fourth studio album by American singer-songwriter Katy Perry, released on October 18, 2013 by Capitol Records. Recording for the album began in 2012, following the March 2012 re-release of her August 2010 album Teenage Dream, subtitled The Complete Confection, and continued into the following year. The album's composition was largely inspired by Swedish dance music artists such as Robyn. In order to create her desired sound, Perry worked heavily with Swedish producer Max Martin, while also enlisting past collaborators Dr. Luke, Cirkut, Greg Wells, Benny Blanco, and StarGate, as well as new collaborators Klas Åhlund, Bloodshy, and Greg Kurstin.
"Roar" was released on August 10, 2013 to American radio stations as the album's lead single and it has since topped the US Billboard Hot 100, while peaking at the top 10 of twenty-five countries. "Dark Horse" featuring rapper Juicy J was released on September 17, 2013 on iTunes as the album's first promotional single. "Walking on Air" was released on September 30, 2013 as the album's second promotional single. "Unconditionally" was released as the album's second single on October 16, 2013.
