Apex: Rudresh Mahanthappa and Bunky Green (Thursday) Mr. Mahanthappa, an alto saxophonist with a searching intelligence and an incisive instrumental voice, recently established a collaborative rapport with Mr. Green, a fellow alto player more than 35 years his senior. Apex is their resulting group, and the name of their album, now out on Pi Recordings; its powerful rhythm section, resurfacing here, consists of Jason Moran on piano, François Moutin on bass and Damion Reid on drums. (Through Oct. 17) At 7:30 and 9:30 p.m., Jazz Standard, 116 East 27th Street, Manhattan , (212) 576-2232, jazzstandard.net; $25. (Chinen)
Brooklyn Jazz Wide Open (Wednesday) Presented by Connection Works, a Brooklyn nonprofit jazz organization, this concert features the John Hollenbeck Large Ensemble, the ambitiously contemporary orchestra led by Mr. Hollenbeck, a drummer and composer. Also on the bill is Works — a trio consisting of the flutist Michel Gentile, the pianist Daniel Kelly and the drummer Rob Garcia — with a featured guest turn by Tony Malaby on tenor saxophone. At 8 p.m. (doors open at 7:30), Littlefield, 622 Degraw Street, Gowanus, Brooklyn , (718) 855-3388, littlefieldnyc.com; $14, with a $6 drink minimum; $10, with a $3 drink minimum for under 21.

Tomas Fujiwara and the Hook Up (Saturday) Mr. Fujiwara, a drummer of acute reflexes and subtle control, just released his debut as a leader, “Actionspeak” (482), from which he draws here, with partners like the guitarist Mary Halvorson and the tenor saxophonist Brian Settles. The album’s aesthetic gestures toward mid-1960s Wayne Shorter: sleek, enigmatic postbop, more suggestive than demonstrative. At 10 p.m., the Stone, Avenue C and Second Street, East Village , thestonenyc.com; $10. (Chinen)
Vijay Iyer and Craig Taborn (Saturday) Mr. Iyer and Mr. Taborn are both pianists, both improviser-composers, both drawn to interrogatory frictions. They perform successive solo sets here — Mr. Iyer likely drawing from “Solo” (Act), an impressive album released last month — as well as an intuitive dual improvisation, on two adjacent Steinway grand pianos. At 8 p.m., Miller Theater, at Columbia University, Broadway at 116th Street, Morningside Heights , (212) 854-7799, millertheatre.com; $25. (Chinen)
Darius Jones Trio (Thursday) Led by the robustly creative alto saxophonist Darius Jones, this working trio expands on the ideals of post-1960s avant-garde jazz, with restlessness and rigor. The group appears here on a new “Loft/Lab” concert series organized by the free-jazz blog Destination Out (destination-out.com) and held at a loft space near Madison Square Park. At 8 p.m., SALT Space, 1158 Broadway at 27th Street, Fifth Floor , saltspacenyc.com; $10. (Chinen)
Snake Oil (Tuesday) All quackery aside, this hard-nosed collective — with the alto saxophonist Tim Berne, the pianist Matt Mitchell and the drummer Ches Smith — will pursue an agenda of rhythmic intensity and abstract epiphany. At 9:30 p.m., Korzo, 667 Fifth Avenue, at 20th Street, Park Slope, Brooklyn , (718) 285-9425, myspace.com/konceptions; $5 suggested donation. (Chinen)
