First time Concert Photography in low light, which lens should I get?

So this sunday is going to be my first time shooting an indoor, low light concert. It's a small club with a capacity of about 150 people. So there isnt anything like a photo-pit of course haha! I want to shoot multiple bands there.

I rented the Panasonic S1H body for the weekend and also the Panasonic Lumix S PRO 24-70mm f/2.8 Lens.

Now im wondering, should i also rent the Panasonic Lumix S PRO 70-200mm f/2.8 OIS Lens?

Or can I do it with the 24mm-70mm alone? And do you have some tips for shooting in these conditinos with this particular camera?

Thanks everyone!
