Hi everybody!
I plan on attending the nbhd concert at Barclays center on Nov 22nd and have a few questions since it first time attending a concert. I live in queens and the events at Brooklyn so I’m worried mostly about how late the concert might end. Does the event start at 6 as listed or is that when the doors open? How long do the openers perform for? Around what time will the event most likely end? How long will it take to exit the building? I wanna be home by 11:30 latest. If anyone could answer my questions and put my mind at ease I’ll forever be indebted :)
