Nublu Sessions, the latest from inventive New York City collective Wax Poetic, is an airtight stunner whose swirl of styles ranges from trip-hop and acid jazz to spoken word. Guest vocalists like the great N'Dea Davenport (formerly of the Brand New Heavies) help make it a transcendent listening experience. But it's a reserved Grammy winner who provides the disc's peak performance: On the tropically tilted R&B cut ''Tell Me,'' Norah Jones infuses her natural restraint with an intoxicating vibrancy that will have you hitting repeat repeatedly.
