It seems like it's been a while since the latest acts were announced for any of the December ATP festivals. In fairness, the organisers have probably been quite busy enough with all the I'll Be Your Mirror stuff going on. Anyway, the newest additions for the Jeff Mangum-curated event are here. And they are good. They are...

Joanna Newsom
Thurston Moore
Sebadoh
Tall Firs
The Mountain Goats
Sun Ra Arkestra

They join these, who were previously announced:

Jeff Mangum, Fleet Foxes, Boredoms, Yann Tiersen, Thurston Moore, Low, Scratch Acid, The Fall, Superchunk, Young Marble Giants, The Magic Band, The Olivia Tremor Control, Mike Watt & George Hurley perform the songs of the MINUTEMEN, The Raincoats, Robyn Hitchcock, Group Inerane, A Hawk & A Hacksaw, Elephant 6 Holiday Surprise, Half Japanese, Tinariwen, The Apples in Stereo, Colin Stetson, Micachu And The Shapes, Lost In The Trees.

The festival runs from 2-4 December 2011 at Butlins Holiday Camp in Minehead. More information on that and the other, triple-curated weekend, are available from the official website.
