I agree with all the other posts above. An absolutely great concert. I was worried that the crowd will not be that much into the show and I'll be the only one standing in the middle of the floor, to my suprise everybody was standing and rocking it out. All the guys sounded great. MM's drum solo was fantastic too. As far as the photography goes, I'm definitely 100% sure it is Rosemont Theater's policy. I saw couple other concerts there and they enforced that same rule.
Sorry to hear that. While Rosemont Theater is a great venue with great sound quality, just for future reference for anybody who wants to see any concerts there, do not buy tickets on the extreme sides of the balcony 'cause you'll not be able to see half the stage.
