Around what time do main artists more or less come out to perform?... I'll be working so I wanna see if I'll make it or not

It really depends on the artist...

I went to the Erykah Badu concert on the 22nd and she didn't come out until 12:13am lol, it was her show but she gave at least 10-13 artists the chance to perform, doors opened at 7, show was supposed to start at 8 but started alil after 9 but overall it was a good show!!!!

Yeah they get there around 7/8 to get ready. Its good to come around 9 or 9:30 for good parking. It gets more lit around 10/11 so you'll have time. Artist are usually out before 10

If show starts at 8p - Typically 10/11p after opening acts if any. You can always call or ask security at the door what time the artist is schedule for.
