Greg Kot at the Chicago Tribune has the scoop.

Just got off the phone with Julian Casablancas and he confirms that the Strokes will indeed be headlining Lollapalooza this summer as first reported here a few weeks ago.

He says he’s pretty stoked about the band’s string of festival dates this summer. “We’re getting the biggest offers of our career,” he says. “It feels great, because I remember people writing things like ‘We’ll see if they’re still around in 10 years’ when we first came out.”

Besides preparing for his solo tour, which lands at the Vic Theatre on April 6, Casablancas says the Strokes are wrapping up their fourth studio album, and first since 2006. “I think it’ll be out in September,” he says. “I’ve written a lot of melodies for it, but the other guys have also contributed a lot more: melodies, choruses, parts. It’s way more collaborative. So it’ll have a different feel than our other albums.”

The Strokes are likely to be joined by Lady Gaga, Arcade Fire, a reunited Soundgarden and Green Day as Lollapalooza headliners Aug. 6-8. Time Out Chicago is reporting that Phoenix will be the sixth headliner.
