A few weeks ago, Greg Kot scooped everyone with news of three of Lollaplooza 2011′s headliners. Now hot on the heels of news that Pitchfork Music Festival 2011 tickets going on sale on Friday, rumors of its line up are making their way around the interwebs.

First off, Chicago Reader’s Gossip Wolf claimed it has the scoop on this year’s Pitchfork yesterday and named Superchunk as a headliner. Other acts said to be on the festival’s bill, according to Gossip Wolf, are the newly reunited Dismemberment Plan (who just rolled through town a week ago), TV On The Radio (who have a new album on the way), Odd Future and Atmosphere. Also, remember the “Don’t Look Back” series? Wolfy says expect Queensryche and a reunited That Dog partaking this year. (Ed. Note: Yeah, these last two were jokes that went over our head)

But Gossip Wolf isn’t the only one with the rumors. Music Blog Product Shop NYC stated back in early January that it’s hearing rumors a reunited Pulp will play the festival along with Deerhunter, Guided By Voices, Drake(?!?), Gang of Four and Twin Shadow. Perhaps they’re getting the rumors from the 100+ spam comments on the post.

Finally, Consequence Of Sound points out that Os Mutantes have confirmed their Pitchfork appearance on twitter. So, at least there’s that.

With tickets going on sale tomorrow, I’m sure we’ll find out the full line-up sooner rather than later.
