'Storm Area 51' Creator Cancels Event. Organizer Matty Roberts claims the cancellation is due to a dispute with the owner of the festival's setting. A statement on the 'AlienStock' festival website says it didn't want to be "FyreFest 2.0.". The event was originally set for Sept. 20 in Rachel, Nevada. Due to the lack of infrastructure, poor planning, risk management and blatant disregard for the safety of the expected 10,000+ AlienStock attendees, we decided to pull the plug on the festival, Alienstockfestival.com, via statement. Instead of 'AlienStock,' there will now be a party at the Downtown Las Vegas Events Center. The 'Area 51 Party' will be held Sept. 19 at 8 PM. Roberts, a 21-year-old California native, originally started the Facebook event, "Storm Area 51 – They Can’t Stop All of Us.". Millions went on to RSVP, prompting the U.S. government to issue a warning about approaching the area
