Coachella? Sold out. Bonnaroo lineup? Known. Sasquatch!? Check. Those crazy huge European festivals? As much as those lineups are drool-inducing, who's got the kind of cash laying around to be able to hop on a plane to Spain? Not me. Given all the above, Idolator is keeping Fest Mania alive by getting the speculation started about who might play Lollapalooza this year. One band, Son Volt, is already known. The Idol folks think it's probably a good bet that Smashing Pumpkins, Wilco, and Kanye will be there; go on to hope for Air, The Shins, Arcade Fire, and others; and then throw in a total curveball by dropping Prince's name.
