MANSFIELD -- As one of the funk-rock hybrids that rode to success in the wake of the Red Hot Chili Peppers, 311 never quite equaled that band in terms of record sales or public awareness. But if singer Nick Hexum lacks Anthony Kiedis's sex appeal and bassist P-Nut doesn't have Flea's oddball factor, Friday's performance at the Tweeter Center revealed how the band has managed a successful career while staying mostly under the radar.
A key factor is 311's musicianship. Drawing heavily on not only funk but also Caribbean forms such as reggae, ska, and dub demands a tight rhythm section, and P-Nut and drummer Chad Sexton were easily up to the task. Sexton compensated for hiding behind his kit for most of the show by taking a drum solo during ''Applied Science" that showed off what he had been doing almost invisibly, with the rest of the band eventually joining in to pound on a line of toms and cymbals that had been added at the front of the stage.
