Depending on how you see her, Aussie singer Sia is either a lounge-pop fixture (thanks to her collaboration with Zero 7 and frequent appearances on Grey’s Anatomy and Six Feet Under soundtracks) or a dance icon in the tradition of her hero Cyndi Lauper. But why not have it both ways? Lately, she’s been writing songs for Christina Aguilera and dating Le Tigre’s JD Sampson, recording jangly deep cuts from her forthcoming album We Are Born that meld her soulful voice with frothy beats and uplifting, spirited lyrics. While an M.I.A.-style makeover would be ideal, Sia live in concert is the best of both worlds. Take that, Hannah Montana. With Girl in a Coma.
