Concert at 7pm Tonight 11/13

Hello all, so I don't normally go to concerts. Billie is actually my 3rd artist I will go to see. So I'm attending her concert in Chicago tonight and thing is I don't have any idea what time is a good time to show up to the line, I'm going with someone but we're meeting there, I have the tickets on my phone though.

I'm actually pretty excited because this my first time going to a concert of my choice, the other two I was invited to and didn't want to say no. I think showing up at 5 is good? Too early? Also are there any tips from people who normally attend concerts? Thanks for your help in advance.
