Before you ask us "Why on earth is Complex covering a 9-girl Korean pop supergroup?" we're covering it because they're a fucking 9-girl Korean pop supergroup. Girls Generation has just made their US debut—now signed to label powerhouse Interscope Records—with their new single for "The Boys" along with their brand new music. There's something about these girls that shout "the new Spice Girls?" but we'll hold onto that thought for now. The girls will introduce themselves to America when they hit Madison Square Garden on October 23.
