Release date: November 2008
I Am... Sasha Fierce is the third studio album by American recording artist Beyoncé Knowles, released on November 14, 2008 through Music World Entertainment and Columbia Records. In its initial release, the album was formatted as a dual disc, intending to market Knowles's contrasting facets of artistry. The first disc, I Am..., contains slow and midtempo pop and R&B ballads, while the second, Sasha Fierce (named after Knowles' on-stage alter ego), focuses on more uptempo beats that blend electropop and Europop genres.
In an interview with MTV, Beyonce spoke about the content of the album: "I'm a human being. I cry. I'm very passionate and sensitive. My feelings get hurt. I get scared and nervous like everyone else. And I wanted to show that about myself. It is about love. I'm a woman, I'm married, and this portion of my life is all in the album. It's a lot more personal. I'm very private and I don't talk about a lot of things, but there are certain songs that are on the album that are very personal. It's my diary. It's my story... I still have my album of fun songs."
I Am... Sasha Fierce debuted at number one on the Billboard 200 chart, with first-week sales of 482,000 units, earning Knowles her third consecutive US number-one solo album. The album earned at least seventeen platinum and one diamond certifications in separate worldwide markets. As of March 2013, I Am... Sasha Fierce had sold over eight million copies worldwide, with its digital tracks accounting for an additional 25 million units. The album garnered eight Grammy Award nominations at the 52nd annual ceremony, eventually collecting five wins.
