In the Times:

ROY CAMPBELL’S AKHENATEN ENSEMBLE (Tuesday) Drawing on the expressive and searching music from his most recent album, “Akhenaten Suite” (2008), the trumpeter Roy Campbell leads a group with Billy Bang on violin, Bryan Carrott on vibraphone, William Parker on bass and Zen Matsuura on drums.

MARK FELDMAN AND SYLVIE COURVOISIER (Sunday) As a pianist and composer, Ms. Courvoisier pursues intricacy and rigor; Mr. Feldman, a violinist, favors plangent power.

At 10 p.m., the Stone, Avenue C and Second Street, East Village, thestonenyc.com; cover, $10. (Chinen)

FIELDWORK (Monday) On its potent new album, “Door” (Pi), this trio throws down a characteristic gantlet of jagged melodies and asymmetrical forms. The heart of the group’s sound is an ever-shifting rapport between the pianist Vijay Iyer, the saxophonist Steve Lehman and the drummer Tyshawn Sorey. At 7:30 p.m. (doors open at 7), Le Poisson Rouge, 158 Bleecker Street, Greenwich Village, (212) 796-0741, lepoissonrouge.com; $15. (Chinen)

At the Stone, Avenue C and Second Street, East Village, thestonenyc.com; cover, $10. (Chinen)

? ROBIN HOLCOMB (Friday and Saturday) Ms. Holcomb seeks out meditative spaces as a pianist and singer, and softens her avant-garde urges with an enveloping lyricism. On Friday she shares a bill with Flutterbox, an experimental pop duo. On Saturday she revisits “Larks They Crazy,” an off-kilter classic featuring Marty Ehrlich and Doug Wieselman on reeds, Dave Hofstra on bass and Kenny Wollesen on drums (who will all join her).

KNEEBODY WITH THEO BLECKMANN (Sunday) Blending rock, jazz and funk in a convincing amalgam, Kneebody draws on the skills of improvisers like the trumpeter Shane Endsley.

At 9:30 p.m., Joe’s Pub, at the Public Theater, 425 Lafayette Street, at Astor Place, East Village, (212) 539-8778, joespub.com; cover, $15, with a two-drink minimum. (Chinen)

DONNY MCCASLIN AND BEN MONDER (Sunday) Weighing Latin American rhythms against a rock-inspired forward thrust, the fearless tenor saxophonist Donny McCaslin and the ruminative guitarist Ben Monder team up with a strong bassist (Boris Kozlov) and a serious-minded drummer (Adam Cruz). At 10 p.m., 55 Bar, 55 Christopher Street, West Village, (212) 929-9883, 55bar.com; cover, $8. (Chinen)

MATTHEW SHIPP (Monday) Mr. Shipp’s pianism can be prickly but it’s rarely off-putting, because his even his free improvisations tend to follow a faintly linear path. He performs solo here, as on a thoughtful recent album called “One” (Thirsty Ear). At 8 and 10:30 p.m., Blue Note, 131 West Third Street, West Village, (212) 475-8592, bluenote.net; cover, $15 at tables, $10 at the bar, with a $5 minimum. (Chinen)
