Last week, Greg Kot reported that Radiohead and Nine Inch Nails will be headlining this year's Lollapalooza. Mum's the word around Lolla-HQ, but fans don't seem to care: the first round of tickets--at only $60 a pop--sold out in twenty minutes. They'll be another chance to spend your dough on the 25th, but officials won't be giving away the lineup until next month.
