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.
