I Am... Sasha Fierce

Structured as a double album, the third studio effort by the global superstar formally introduces her aggressive, highly confident alter ego. The first half focuses on traditional, emotionally resonant acoustic pop ballads like 'Halo', while the second disc transitions into massive, synthesizer-driven electro-pop club anthems, highlighted by the cultural phenomenon 'Single Ladies'. The massive commercial smash earned her a record-breaking six Grammy Awards in a single night.
