Thousands of fans treated to sight and sound spectacular during trio’s Miami Music Week ‘One Night Stand.’ By Akshay Bhansali and Adam Stewart Swedish House Mafia Photo: 2010 Denise Truscello MIAMI — Swedish House Mafia attempted — and executed — a spectacle of mammoth proportions on Miami’s South Beach shore on Saturday. With close to 15,000 masked fans checked in and hundreds of others watching and dancing alongside a massive tent, the house music super-group treated their fans to the nine-hour mini-festival that was “Masquerade Motel: One Night Stand.” While the three Swedes were the headliners, their supporting lineup alone was worth marveling over: Junior Sanchez, A-Trak, Armand Van Helden, Max Vangeli, AN21, Dirty South, and Pete Tong (who also emceed the event) were among the big-name performers. But when it came time for Axwell, Steve Angello and Sebastian Ingrosso to take the stage, it was clear this show would be like no other Miami has seen. The curtain dropped to reveal a massive, 40-foot structure adorned with LED screens, lights, pyro and speakers. And with the trio standing at the center of it all, the crowd exploded. Swedish House Mafia opened with their late-summer 2010 anthem, “Miami 2 Ibiza,” which was followed by “Dynamite,” a new track by Alesso, who was recently signed to Ingrosso’s Refune Record Label. Then followed the stream of new music fans had been eagerly awaiting. SHM dropped a block of fresh tunes, a highlight of which was an off-center, Arabian-style techno monster that the crowd went berserk for, as the guys danced onstage in sync with their fans. Then there was a remix of deadmau5 ‘s “Strobe.” Next was Marco V’s “Reaver” and a mash-up of Angello’s “Show Me Love” and “KNAS,” which kicked the show into overdrive, accompanied by a stunning visual display.
