Omfg, speaking of Flusher, my mother was planning on buying us tickets to see him but backed out because she heard about it only a few days before he played at the nearby arena, and she thought that they would've sold out at that point. She literally checked out the night before, and there were TONS of tickets still available.
Meanwhile, she got the Ariana tickets almost immediately after they went up for sale, and the entire front section was already sold out.
