Atoms for Peace

No Soundgarden?

No way - too many posibble headliners on this list

I would willingly soil myself to see Atoms for Peace AND Pavement in one weekend.

The Austin 360 the contains this article also admits there is a 0% chance that some of these bands will play. They just basically threw a wishlist/I heard it on the internet list together and called it a rumor.

My thoughts on a few of these...

The Eagles - low probability - they play really big arenas
Phish - intriguing
Flaming Lips - I think yes
Robert Plant and Band of Joy - Probably not - already here this summer
Blues Traveler - maybe - they've been making the rounds recently
Erykah Badu - good probability
Band of Horses - good probability
Gogol Bordello - hope so!
Spoon - If they headline, yes
The Band of Heathens - this makes sense
Norah Jones - low probability
Phoenix - high probability
Deer Tick - high probability
Vampire Weekend - maybe
Jack White and some band of his - pretty good chance
Nas & Damian Marley - pretty good chance
Black Keys - lots of buzz - maybe?
Sharon Jones and The Dap Kings - if they have a new CD, maybe
Alpha Rev - almost certainly
Neil Young - geez, wouldn't this be something? But I think not.
Alejandro Escovedo - possible
Amy Cook
Gaslight Anthem
She & Him - Yes, instead of Vampire Weekend
Broken Bells - I would think this is a good probability

And what about...
Esperanza Spalding
Dan Black - have heard rumors in different places
Jacob Dylan - with his new band
Justin Townes Earle
Carolina Chocolate Drops - one of the buzzed about bands from SXSW
Kat Edmondson
Sarah Jarosz
The Scissor Sisters
Black Joe Lewis and the Honeybears
The Constellations

I would love to see the Waco Brothers do ACL. They have a hell of a stage show.

Claire, There have been Eagles lyrics posted on Billboards that were previously ads for ACL and in the Austin Chronicle. I think there is a very High probability that they will be there.
