contains slow and midtempo pop and R&B ballads, while the second, Sasha Fierce (named after Beyoncé's on-stage alter ego), focuses on more uptempo beats that blend electropop and Europop elements. In its original release, the album was formatted as a double album, intending to market Beyoncé's dichotomous artistic persona. It was released on November 12, 2008, by Columbia Records and Music World Entertainment. Sasha Fierce is the third studio album by American singer Beyoncé.
