I'll kick it off. Random order under the headliners.
And god damn right I picked Modest Mouse. (Yes, over Morrissey.)
MODEST MOUSE PIXIES PAVEMENT
Morrissey Atmosphere Belle & Sebastian Blitzen Trapper Built to Spill Cursive Stars Triumph of Lethargy Skinned Alive to Death Girls Japandroids Minus the Bear The Black Keys Kay Kay & His Weathered Underground Cloud Cult Cave Singers Cold Cave Wolf Parade Sebadoh Feral Children The Mountain Goats The National Broken Social Scene Band of Horses The Avett Brothers Bloc Party The Roots Hey Marseilles Iron & Wine Los Campesinos! The New Amsterdams
Even though I love them I'm surprised that you would want Modest Mouse to headline... I've seen them twice and both times they were so fucked up they couldn't play or sing... it was rather unfortunate actually...
I'm completely with I8 here. He started this thread to invite wishlists, so you have zero room to bash his picks (especially including your track record from what I've seen so far) but if we're going to be serious about these decisions, Modest Mouse is one of this generation's greatest bands. I don't know which show(s) you went to, but Modest Mouse has played some of the most energetic, entertaining sets I've ever beheld.
I would love to see them play a headlining set. Realistic? Perhaps not. But on my wishlist as well? Hell yes. By the way, nice pick of Stars, I8 - another good wishlist choice.
