FWIW, I do know that a lot of artists do use vocal tracks to "boost" their sound rather than simply lip sync. Don't know if that was what she was doing. In one of my earlier groups we had a manager who was insistent that we do that sort of thing, and we eventually fired him because I wanted no part in it. I do remember seeing the vocal group "Point of Grace" once where they performed to tracks (they had no band anyway), but there was a glich and the vocals for the next song started playing at the end of one song. Clearly they were "boosting" their vocals. The really funny thing is, they then did an completely acapella song which clearly had no "boosting" trac, and it sounded perfect.

I do think it's very telling the Ashlee felt the need to blame her band for this.
