I know I am a little late in saying this, but singers like Ashlee Simpson are exactly why I do not go to rock concerts. As to be expected, most artist want to put on a good performance but since many cannot bring their A game night after night, many choose not to sing live and end up lip-syncing. I am not down with that. If I am going to pay $70 to attend a concert, god damn it, I want to hear them actually sing. Heck, if I want to listen to the CD version, I would stay home and blast my stereo.
