With his wide leaps between long tones and a sometimes generous use of space, trumpeter Wadada Leo Smith nods occasionally to 20th-century European concert music. But he's also one of the modern improvisers most grounded in African-American vernaculars; he's the stepson of Mississippi bluesman Alex Wallace, and he played for a spell in Little Milton's blues band. Smith's projects are all over the map, but often have this much in common with the blues: the byplay between a strong voice — his horn, in this case — and percussive strings.

Two kinds of people consume Christmas music: those who actually like the stuff, and folks who need something listenable on hand in case seasonal visitors insist on some ornamental mood music. For both groups, two new jazz brass albums should do the trick. Critic Kevin Whitehead reviews.

In the last few years, some enterprising younger players have reinvented the piano-bass-drums jazz combo. It's not just that these trios play contemporary pop; it's also a shift in attitude. Vijay Iyer's trio doesn't worry about swinging all the time, although the buoyancy of swing inflicts its rhythms as much as hip-hop does.
