The Sasquatch! 2011 lineup announcement is due soon, ending rumors with news of this year's headliners, lineup and tickets. The Sasquatch! 2011 lineup announcement will happen this year at a live performance on Sunday, Feb. 6. It's a Sasquatch! launch party that will take place at Showbox at the Market. The Thermals, Das Racist and Mad Rad, along with comedian Todd Barry as host will all perform at the lauch party.

Last year's launch party featured performances by Atlas Sound, Surfer Blood and Fresh Espresso at the Crocodile in Seattle. So far, headliners Foo Fighters are the only act to be named for the 2011 festival, and will be wrapping up the newly added Friday night night. Tickets are on sale now.

So here's the skinny on the 2011 Sasquatch! festival: the dates are May 27 - 30, which comes as no shock as the festival has always been on Memorial Day weekend, and that happens to be Memorial Day weekend for 2011. That also means that they've added on a day ... the three day event has now become four epic days! This will also be the 10th anniversary of Sasquatch!.

Sasquatch! lineup rumors right now include Wolf Parade, Modest Mouse and of course Arcade Fire, who seem to top the rumor list of every major festival.
