Chicago’s Lollapalooza festival, which comes to Grant Park 8/2-4, won’t announce its lineup until next month. But the Chicago Tribune‘s Greg Kot, who is never wrong about this stuff, is reporting that this year’s slate of headliners includes Mumford & Sons, Phoenix, Vampire Weekend, and the Killers. Further down the bill, the Postal Service and the National will also play.

Lolla usually hosts two headliners per day, so there’s still plenty of time for the festival to find a couple of big names. But right now, that’s not an especially inspiring lineup, is it? The Killers and Phoenix have both already headlined Lolla in recent years, and Vampire Weekend headlined Chicago’s much smaller Pitchfork Festival just last year. Lolla is usually able to stunt hard enough to land a Black Sabbath or a Lady Gaga — someone who usually doesn’t play festivals and who you might be curious to see even if you’re not a huge fan. Maybe they’ve got someone like that in their back pocket; we’ll find out soon enough.
