A Funk Odyssey

By replacing funk’s earthy grit with pixie dust, Jamiroquai’s Jay Kay makes pleasing retro-flavored dance music with gleaming surfaces and no inner life whatsoever; his group’s new album is more Gap Band than P-Funk. ”Odyssey”’s jams are dolled up in some fancy finery, though, with lush, groov-alicious arrangements that can entice even the most recalcitrant booty to get its freak on.
