Depends on who's playing and how many bands there are. I just attended a concert on Wednesday with three bands that started about 7:00 p.m. and lasted till almost midnight. The last time I went to a concert like that there it didn't start until 7:30 and only lasted till about 10:30 for the headliner and an opening band
Usually until 11
Around 11ish
11 work
I've heard they have to end by 11. For the neighbors
Sorry I am no help to you. I was there for a High School graduation. One thing I can help with. Park close to an exit and walk in. Long walk but that way you can get out. I heard some people sat there for 20 plus minutes without moving waiting to exit.
