Enter the Kung-Fu Girls. These sisters, aged 15 and 17, are ready break into and put a smile to the scene. I've gotta say The Kung Fu Girls have some pretty happy music for happy people. They've been decribed as "Cute, happy, lollipops and rainbows". And why wouldn't they be happy? They're only 15 and 17 and get to play at cool clubs [The Knitting Factory]. They've got wicked cool real names [Mia & Ava Koo]. And their debut album is dropping this September.
