3x3 Women Who Rock Edition: Amy Winehouse, Tegan & Sara, Imogen Heap

To accompany our "Women Who Rock Right Now" feature, we've complied a 3x3 comprised of women who do just that. We start with everyone's favorite lush Amy Winehouse, who delights her hometown audience with her soulful croon. Then we head over to Toronto to get a dose of Canadian twins Tegan and Sara, who rev up an adoring crowd with their infectious hooks and heart-on-sleeve folk-punk. We wind things down with a whimsical performance from Imogen Heap, who layers mind-bending ambient-electronica with indie-rock sensibilities for a London crowd.
