Halloween is here and Tribal Sessions are throwing an epic acid party at Fire London. Dress your scariest and get ready to dance the night away with Chicago’s house music don DJ Pierre, Dark Sky, Anek and Jozef K. In terms of style, think old skool rave, complete with acid house faces, baggy clothes and lurid colours galore. There’s prizes for the best dressed, spooky games and all manner of mischief to be wrought. Over 18s only.
