Question about Waller Creek Amphitheater

Hi y’all! I need advice.

I’m going to see Majid Jordan tonight and I’ve never been to this amphitheater. Doors open at 7 pm, what time do you reccomend i arrive? I’m super unfamiliar with concerts in the US. I’ve been to 2 this year and everything it has been polar opposite experiences, so i’m lost!

Thank u guys 🙂
