For Ween's sizable cult fan base, a show by the New Hope, PA, institution is a holy event, a unique collision of the absurd and the sublime. Even if you haven't drunk the Kool-Aid, you have to admire the band's chameleon-like range: metal, country, psych-pop, funk, Tex-Mex, you name it. There's no new release to flog, just two decades' worth of timeless tunes.
