Lady Gaga

Lady GaGa goes live at Interscope's Cherrytree House, paring down the electro-backdrop and highlighting her powerhouse vocals (with and without a little help from Auto-Tune). The stripped-down version of her smash hit "Just Dance" and beatbox-and-keys take on "Eh, Eh" are sparkly enough gems to entice your eardrums. But our fave is the bold, spare reworking of "Poker Face," featuring only piano and Lady GaGa sidling up to it, working her best inner cabaret diva. (OK, so maybe any kind of diva isn't so "inner" when it comes to Lady GaGa.)
