That's Doug Martsch of Built to Spill behind that hat.It's the end of Day 1 of Pitchfork Music Festival here in Chicago, which by Sunday, should see 40 bands play and welcome 50,000 -- ahem, hipsters -- through the fences of Union Park. More than a few bands who have made their way through St. Louis in the past year -- and some who will be here later on -- are scheduled to play this weekend.
