The Aragon Ballroom in Chicago holds 5500 people.
My vote would be for the Red Hot Chili Peppers, Bjork, and Rage Against the Machine so they won't pollute any more Coachella lineups.
Bring back Screaming Trees, My Bloody Valentine, The Stone Roses, Ride, Pulp, Roxy Music, and Manic Street Preachers (w/ Richey, who was found alive by Goldenvoice, living in Borneo amongst natives). That would be hot.
