Field Day takes place on August 1, and like all of London is going. But you probably knew that already.

What you probably didn’t know is that Optimo lynchpin JD Twitch has been added to the already bursting-at-the-seams bill, as well as Wild Geese (presumably not a Wild Beasts side project) and Gaggle, and that the full stage line-ups have been revealed, along with a bunch of info about the various after-parties surrounding the festival. Right, so those stage line-ups:

There’ll also be a Guardian Tea Room Tent, which promises to "offer a touch of refinement to proceedings with lashings of freshly brewed tea and home-made cakes to help you recharge your batteries whilst perusing the paper." Meanwhile, the newly announced Time Out ‘Do You Come Here Often’ tent collaborates with Eat Your Heart Out and the Take Courage Gallery to "bring together the cutting edge of live art in London." You know, just in case Audion, The xx, Drums of Death, Twitch et al aren’t enough for you.

The two official Field Day after-parties have also been announced. The first takes place at South London’s fledgling Cable club, and hosts DJ sets from Erol Alkan, Little Boots, Aeroplane, Fake Blood, JD Twitch, Casper C, Skull Juice, Crispin Dior and Stopmakingme. Then there’s a second event happening at the Amersham Arms, New Cross – that one features Rusko, the No Pain In Pop crew and special guests.
