When Hamiett Bluiett's baritone sax honks out the riff from the O'Jays' "For the Love of Money," it's clear that not only are several genre fences being run down, the World Saxophone Quartet is having the time of its life driving the bulldozer. Not that Rhythm and Blues, a set of six soul and blues classics matched with three originals, lacks subtlety. A ruminative, slowed-down "Let's Get It On," the natural encore hand- clapper "I Heard That" (one of Bluiett's two compositions here), and "Night Train," the James Brown-by-way-of-big-band mover--just three sublime highlights--help make this a gleeful, deeply felt work of very, very human art
