Later on, the Guggenheim’s annual, and usually tame, Young Collectors Council celebration swelled to an epic dance party in the museum’s spiraling rotunda, thanks to tunes provided by DJ Afrika Bambaataa, and boatloads of tequila. While “young” may be a relative phrase in the world of art collecting, some true youngsters on hand included art buffs Bee Shaffer, Indre Rockefeller and Nell Diamond, along with Dree Hemingway and Peter Dundas, who wore his signature evening shades. This marked the first appearance by Mr. Dundas after being named creative director at Roberto Cavalli. While he remained mum on the details of his new gig, he did reveal that he would be jetting off to Los Angeles the next day for LA. Vintage purveyor Cameron Silver was also taking off the next morning, heading to Malaysia.
