I heard the album the other day. I have to say it's not a "bad" live album. However, as Sydo said, its kinda boring. It just isn't necessary really, there's nothing really special about it, so I mean if you were in the mood for listening to a Maiden live album, you'd put on Live After Death obviously not that. ALso there is way too much from BNW on Disc 1, I would only want to listen to disc 2 I think.
I saw the videos on it though... Brave New World's video looked great. But I am guessing that was the TV broadcast version whereas the DVD is re-edited by Steve.
