You just have to walk down out of that area instead of over (even though it appears you must walk left).
A concert? Hell yes. I hope I get to put Zell on screaming lead guitar. I was so pumped when Cid announced the "journey" and Zell ditched the hot dog line after getting freaking pumped himself. I'm happy with FF8's maturity level. We've got assassination, gloom, death, cursewords...it's the whole thing, and it's being kept tasteful. It rules.
Zell RULES. If I could live half the way he does, I'd be on top of everything.
