hmmmm....not in specific order...
1996 - Camel Desert Air Rave - Camel Cigarettes spent $1,000,000 on this rave party 30 miles outside of Vegas. they actually flew a plane with people from Germany direct to Vegas - they removed the 1st Class section and put in a dancefloor! best sound and best lighting at any event i've ever been to. the lights were suspended on these cranes 50 feet in the air so it looked like a UFO when you arrived at the party.
1996 - Manumission, Ibiza. Circ du Solei on Acid!
2002 - Subliminal Records at Crobar Miami - nothing better than partying with Fatboy Slim in the VIP room while Darren Emerson and Erick Morillo rip it up
mid 1990s - lingerie/pajama party at the guy who inheritied the Neutrogena Cosmetics fortune house in Malibu. strippers washing themselves in his huge glass shower for people's entertainment. and a barge shot fireworks off at midnight! way cool....
Pimp N Ho in Vegas - Halloween 2001 - so many hotties
Nocturnal Wonderland 2000 - probably the best DJ lineup ever in the US - held on the Polo Grounds where Coachella is held now...
