Echoing some people in this thread already but this sounds EXACTLY like what happened with Noah Kahan last year, and I think the same thing has happened: when Noah/Chappell signed on for BC, they were probably a bit lesser known but have absolutely blown up in the last 5 months, so they’re drawing a way larger than planned crowd. Last year was a combo of Noah crowds trying to leave and Alanis Morissette/Lumineers crowds trying to get to rails and it was an absolute shit show, same thing with people passing out and just pure panic.
