At Haze, which celebrated its grand gala opening, thousands of partygoers mobbed the new nightclub in Aria. World-renowned DJ Tiësto wowed the crowd with his massive electronic sound. He was in awe of the multi-audio and -video sound system controlled from the DJ booth stage after he went track for track without missing a beat for 4 1/2 hours. At one point, a 10-foot, glowing robot “The Kryoman” suddenly appeared firing laser light beams and cannon blasts of oxygen, plus showers of cascading confetti. The Kryoman will be at Haze through this month before returning to Ibiza, Spain. French DJ David Guetta takes control tonight.

While spinning above the crowd, Tiësto tweeted: “Sound check at Haze is sensational. Unbelievable. This is the most beautiful club I have ever seen.”
