Long before the coining of "smooth jazz," catchy numbers like Herbie Hancock's "Cantaloupe Island," Joe Zawinul's "Mercy Mercy Mercy," and the Les McCann-Eddie Harris tune "Cold Duck Soup" enticed pop fans to cross over, however casually or tentatively, into jazz. Now, on veteran bassist Brian Bromberg's Downright Upright, those three songs are vehicles for name-brand smooth jazz players including saxophonists Kirk Whalum, Boney James and Gary Meek, keyboardists George Duke and Jeff Lorber, guitarist Lee Ritenour and trumpeter Rick Braun to do a little crossing back of sorts to show off their mainstream chops. Nobody will confuse the facility of their straightahead solos with real depth, however much emotion they pour into them. But it's an agreeable excursion for all concerned, with Bromberg making the most of his opportunities to lay down melodic lines. Even after the cover versions give way to originals in the same vein, the music stays lively. --Lloyd Sachs
