According to Pasquale Rotella of Insomniac Events: 

"Halloween is one of my favorite holidays. The first Insomniac party I ever organized actually fell on Halloween weekend of 1993. I’m excited to announce that we’ll be back in SoCal for TWO NIGHTS this year with Escape! This dark and twisted adventure will take place on Friday, October 31st and Saturday, November 1st. We’ll have several unique themed stages of music to explore and many more surprises. Bring those positive Insomniac vibes with you and we’ll see you on All Hallows’ Eve!"
