They say the show must go on but that was just not possible for a concert venue in Maryland. Halsey was supposed to perform at the Merriweather Post Pavilion last night but canceled the show last-minute due to a storm. The venue declared a shelter-in-place order, meaning her fans were left stranded. As the venue started to flood, fans ran into the bathroom for shelter and even saw rodents. Halsey tweeted that she would be rescheduling the show but not at that venue.
