Brand New ended at approximately 10:52pm in Atlanta.

I went to the three southeast shows. All slightly different start times. But all done by 11pm.

Miami: MM 7:00pm, BN 9:15pm.
Tampa: BN 7:15pm, MM idk because I left. Wasn't before 9pm though.
ATL: MM 7:00pm, BN 9:10pm.

There's a 45 minute changeover between bands. First one starts between 7-7:15, headliner between 9-9:15. BN plays 17-18 songs headlining and 15 opening. I assume MM does the same.

The Red Rocks show started at 7:30pm with Modest Mouse. They were done around 8:40pm. Brand New came around 9:30pm. Their main set ended at 10:40pm. Then they came back for a 4 song encore that took it to about 11pm. It sounds like your shows starts at 7:00, so yours might end even earlier.

Hey, so it looks like your Philly show will also have Brand New closing, as they did in Red Rocks. We got a 67-minute set from Modest Mouse (15 songs) which some people weren't that happy with, but I felt like it was perfect. My first MM show and I couldn't have been happier. I don't know if you've been to Red Rocks before but there is only one road out of the park, so my wife and I actually left early to beat the traffic, so I'm not sure EXACTLY when Brand New finished their set, but I'd guess it was about 11. The show started at 7:30, so with intermission it was about 3 1/2 hours total. Your show will likely be over around 11:30, if I had to guess.

Hope this helps! Let me know if you have any other questions.
