Ah yes, the topic of "why does this sound like this, but this other one doesn't?!" Simple answer, two different setups, venues, recording techniques, coverage, etc. etc. etc. I could go on.
All you need to know is this - the raw recording will ALWAYS dictate the end product. Although, a recording can be mixed badly, which would make things worse! I refer, of course, to the snare sound that people always mention when talking about the Bowl release vs the bootleg.
Btw, I also remember hearing that Bowl was remixed from the multitrack recording. But really, there's no great mystery here. In fact, because Montreal was specifically designed as a cinema release, there would've been huge attention paid to how it was recorded and treated after that. Think about it. If they hadn't gotten the sound right, that could've been a real disaster when trying to use it for the purpose it was originally recorded for. And while we all know these things get overdubbed at points, it would've been silly to do a lot when it's supposed to show the band in their element.
Anyway, nothing interesting to find out from this as it's just an everyday occurrence. One event would've had plenty of coverage, while the other (Bowl) wouldn't have.

P.s. just because Rio sounded lesser than the (remixed) release on the AWT single CD, doesn't mean that everything can magically improve. It could be down to many factors which I won't go into. Too much to try and cover!
EDIT: I wrote a blurb about Bad Seed's idea that Justin and co. copy the sound of stuff they're set to mix. etc.. Unfortunately, it was lost. Meh! Here's a brief summary, instead...
1. As I mention above, the original band and recording dictate how it will sound.
2. Anyone mixing a live concert will stick to the band's sound and not want to alter it.
And 3. It's in the mixer's best interest to improve upon what's already there, rather than altering it to fit some vision they have. The latter would very probably find them removed from the project!
It kinda resembles what I said, but alas, doesn't have the same feel. But I think the point still comes across. In other words, Justin and co. ain't copying anything. They're being given that sound to begin with. It's essentially the blueprint that they stick to.
