I'm quite sure this "live" question all hinges on how much Atlantic/Epic are prepared to offer her as an advance, or alternatively how reasonable a licensing fee they would charge if Tori wanted to self-release some of this stuff. Judging by the era that she would have signed with Atlantic, they probably have rights to her recordings in perpetuity, and probably the same with Epic, or possibly long-term licensing of those records. Either way, both will probably have a re-recording restriction in place, or be able to lay claim to all of her live recordings during those periods. If either of those labels don't see the commercial potential in advancing Tori some money to release live albums, it's not going to go any further, I don't think. Sad, of course, but probably true.
