On Sunday afternoon, Limp Bizkit played a brief, unauthorized outdoor gig on the roof of a parking garage near Boston's Fenway Park.

The crowd of about 1500 fans discovered the show's secret locale through a local radio station; so did the Boston police, who shut down the illegal concert after a five-song, 20-minute set that included [article id="1447116"]"Nookie" [RealVideo][/article], "Faith," and "Counterfeit."

Boston police did serve a summons to Limp Bizkit's managers for the stunt, but the group is still planning to test its luck with two more so-called "guerilla" concerts in Detroit and Chicago prior to the June 22 release of its album "Significant Other.
