Most people must have heard about this by now. The '80s hard rock band Great White had just started playing when pyrotechnic sparklers on stage began shooting up and ignited the ceiling above them and soundproofing near the stage. Some in the crowd said they thought it was part of the act, but the fire quickly spread through the low-ceilinged building, filling it with thick, black smoke. The death toll is over 80 last I heard. Fucking terrible stuff.
