Break a beer bottle over their head, to wake 'em up and make them feel something, and that's still what we want to do now," frontwoman Karen O. said about handling indifferent fans. "We want to shake the unshakable, to stir things up, and that's a lot of the spirit of "Zero"; it's like 'Come on man! Come on! Just feel something, escape, whatever, whatever the emotion is just feel it!'"
