disclaimer: I know very little about the band in question, I'm asking questions, trying to make as few assumptions as possible.
It's been 10 years since the band split up? Ask yourself a few questions. Are they actually any good anymore? A lot of these concerts will sell out simply because of the name. I seem to remember the name FNM when I was younger, and I seem to remember that they'd been around for a while even then. As people get old, they deteriorate, *especially* singers. I know some people who have been to re-union gigs and been severely disappointed. Not always the case, of course. And for some people it doesn't even really matter if the show is a poor one; they just want to be in the presence of their idols. So if that's you, then you can safely ignore anything I've just said!
As for a girl. Hmm. I found rock concerts great places to pick up girls, and great places to have a fling with a girl you quite fancy. But I don't think it's the best place to begin a relationship with somebody you wanna get serious with. If you get lucky it's likely because she's been worked up by seeing her idols and/or the amount of alcohol consumed, not because she's suddenly realized that
you are they guy she adores.
Then of course, in a more jestful manner, you could look look at it as a numbers game. When you get your Pandora there'll be about 4000 of them in existence. There's a shed load more girls around than that
More seriously: Decide if you really want to see the band, ignoring the girl thing. If you do, go. If you don't, and the girl really does like you, you'll be able to find plenty of other reasons to spend, perhaps much more meaningful, time together.
