London’s Frieze has only been around for five years, but it has rapidly become the UK’s largest and most influential art fair. “Some 151 galleries from 28 countries were chosen to take part this year, drawn from 450 applicants; each has a booth displaying its best pieces — or at least pieces it hoped would sell or provoke… To the extent there is a buzz at Frieze this year, it has centered on the booth run by Gavin Brown’s Enterprise, a New York gallery, which has been turned into a flea market organized by the artist Rob Pruitt.”
