Aiden seem like nice guys from brief clips/times I've seen them interacting with fans; their music is also not nearly as bad is portrayed. Their image is hilariously awful, but you could do a lot worse than see Aiden live at Bamboozle.
Aiden, VersaEmerge, In This Moment and Madina Lake will be doing the entire Warped on the Ernie Ball Stage. Monty Are I, Settings, and Red Car Wire will also be on the stage during parts of the tour as well.
I remember back in 2005 when Aiden was on one of the main stages (I believe).
