I Am... Sasha Fierce is the third studio album by American singer Beyoncé. It was released on November 12, 2008, by Columbia Records and Music World Entertainment. The album was recorded from November 2007 to August 2008, with production handled by Darkchild, Toby Gad, Jim Jonsin, Rico Love, Stargate, Tricky Stewart, Ryan Tedder of OneRepublic, and The-Dream, among others. Although there are no featured artists on the album's main track listing, fellow American singers Lady Gaga and Kanye West appear on deluxe editions of the album. Upon its original release, I Am... Sasha Fierce was structured as a double album and intended to present Beyoncé's dichotomous artistic persona. The first disc I Am... contains slow and midtempo pop and R&B ballads, while the second, Sasha Fierce—titled after Beyoncé's onstage alter ego—focuses on more up-tempo beats that blend electropop and Europop elements. When writing the songs' lyrics, Beyoncé worked with writers in sessions accompanied by live orchestration. She credited both her husband, rapper Jay-Z, and jazz singer Etta James for inspiring her to push the limits of her songwriting and artistry.
