Which Beyoncé album is built around the alter ego Sasha Fierce?

I Am... Sasha Fierce is the Beyoncé album built around her alter ego Sasha Fierce.

Released in 2008, the album was presented as a double record. The “I Am...” disc focused on more vulnerable and personal material, while the “Sasha Fierce” disc emphasized bold, energetic performance songs.

Beyoncé described Sasha Fierce as a stage persona rather than a separate person. The concept helped her distinguish her private self from the confident, highly theatrical character used during performances.

The album produced major singles including “If I Were a Boy,” “Single Ladies (Put a Ring on It),” “Halo,” and “Diva.” The title is sometimes shortened informally, but the official album title includes both parts and the ellipsis.
