Forgotten to buy your Pitchfork Music Festival tickets and just realised it's sold out? Don't despair. The kind souls at Pitchfork have organised a preview concert tonight at Millennium Park and best of all, it's free! Fleet Foxes, Extra Golden, A Hawk and a Hacksaw, and Boban Markovic will be playing in advance of their sets at Union Park this weekend. The show kicks off at 6.30 p.m., but make sure to get there early if you want to find a good space on the lawn. Read UR Chicago's interview with Extra Golden in the online section. - Jennifer
