We were all trying to decipher the cryptic message about a crazy Halloween party involving Sebastian Ingrosso, Alesso, and Otto Knows a few days ago. Well, we can all stop trying to figure this out as the All Mixed Up details have been announced. There will be two events across two monstrous New York spaces on October 27 at Pier 94 and Nassau Coliseum.

All Mixed Up is the first DJ-headlining event ever for Long Island stalwart Nassau Coliseum being dubbed as the Haunted Coliseum. Refune founder and former Swedish House Mafia member Sebastian Ingrosso returns to New York for the first time since Electric Daisy Carnival. Alesso is back after marking his 21st birthday in sold-out style on Governor’s Island and Otto Knows, who was celebrating with his Swedish countryman that day at the Island, and will join him once again on Halloween for what is sure to be an unforgettable night.

A few more details of the event will be announced this week through a series of purposely boggling puzzles, distributed via tweets, hashtags and secret telephone lines – rewarding the most dedicated fans with precious information, including presale codes, prior to the public on-sale on Friday, August 24.
