Warped Tour in the United Center parking lot

Los Fabulosos Cadillacs, Cherry Poppin' Daddies, Greenhouse at House of Blues

I read a review that described the Cherry Poppin Daddies as appalling.  I think that reviewer was too kind.  I spent most of their set fantasizing about beating the lead singer with his mic stand.

Los Fabulosos Cadillacs were great.  I remember the singer had a sorta nonchalant / disinterested style (I think he sang with his hands in his pockets for multiple songs).  I don't know why, but this was more endearing than off-putting.  And the band was fun.
