What kind of lens should I bring to a concert event?

I'm going to a lat e night concert soon and need help deciding on a lens I should bring with me for my Nikon D7000. I'm sitting in the pits, up at the very front row!

I use the 17-55 f/2.8 for that location. Maybe you can rent one if you don't own one. You might do okay with the newish 24-85 lens, considering the low light performance, it's probably okay.eBay is flooded with them right now, too, so you can probably get one for under $400.

None… Odds are you won't be allowed to use your DSLR as most venues have an ban on them and even if you could, we don;t know what lenses you currently own.
