Outside of South by Southwest, no music festival is as absurd in size as the UK-based Glastonbury. In fact, the whole concept of Glastonbury — that 200,000 people willingly buy tickets for a festival which doesn’t announce its complete lineup until only weeks before its start — is sheer mind blowing. But all this is true, which explains why nothing really compares to Glastonbury. Hell, it’s so awesome, Bono even wrote a song about it — and we all know that unless your mucking up a Broadway musical, that’s not something to take lightly.

This year’s Glastonbury is still months away (June 22-26 to be exact), but we already know a few names set to play. U2, Coldplay, and Beyoncé have been confirmed as this year’s headliners, while the rest of the initial bill includes the likes of Chemical Brothers, Primal Scream, BB King, Fleet Foxes, Mumford & Sons, Big Boi, Janelle Monáe, Crystal Castles, Friendly Fires, Warpaint, James Blake, Anna Calvi, Gruff Rhys, and Laura Marling.

No word on when we can expect to see the rest of the bill, but you can keep track of all the latest Glastonbury 2011 updates on Festival Outlook. As for tickets, those aforementioned 200,000 people resulted in a sell-out months ago, so you’ll have to hit the UK-equivalent of Craiglist (though the required pre-registration probably negates that from even working). An official ticket re-sale is also expected for sometime in April, but details are still forthcoming.
