From NYTimes.com:
Georges Aperghis (Thursday) The Miller Theater concludes its season with a Composer Portrait featuring a tremendously exciting prospect: a commissioned premiere by the dramatically provocative Greek composer Georges Aperghis, performed by the superb International Contemporary Ensemble and led by Ludovic Morlot. The program includes four further works by Mr. Aperghis, from 1978 to 2008. At 8 p.m., Miller Theater, Broadway, at 116th Street, Morningside Heights, (212) 854-7799, millertheater.com; $25. (Smith)
Lisa Bielawa and Ashley Bathgate (Thursday) Appearing as part of a two-week series coordinated by the guitarist and composer Gyan Riley, these two busy artists slip into John Zorn’s bare-bones East Village laboratory for an intimate double bill. Ms. Bielawa, a composer and vocalist, taps her colleagues from a touring production of Philip Glass’s “Einstein on the Beach” for an 8 p.m. program of her own vocal works. Ms. Bathgate, the Bang on a Can All-Stars cellist, shares her 10 p.m. set with the pianist Vicky Chow and the percussionist Ian Rosenbaum. At 8 and 10 p.m., the Stone, Avenue C and Second Street, East Village, thestonenyc.com; $10 per set. (Smith)
Caleb Burhans and Todd Reynolds (Friday) These two composing violinists use electronics — processing effects and tape loops — to extend the sounds and compositional techniques available to them. They offer an evening of their recent explorations, which are usually thought-provoking and entertaining, and never entirely predictable. At 10 p.m., the Stone, Avenue C and Second Street, East Village, thestonenyc.com; $10. (Kozinn)
Jeremy Denk (Monday) This excellent pianist has made a specialty in recent years of works by Ives, Ligeti, Beethoven and Bach. Here he offers Book 1 of Ligeti’s Piano Études and Beethoven’s Sonata No. 32 (Op. 111). At 7:30 p.m., Le Poisson Rouge, 158 Bleecker Street, near Thompson Street, Greenwich Village, (212) 505-3474, lepoissonrouge.com; $25 in advance, $30 at the door. (Schweitzer)
Eclipse Quartet (Monday and Tuesday) A Los Angeles string quartet highly regarded for its new-music advocacy, the Eclipse Quartet comes to Brooklyn with a pair of tantalizing programs. On Monday the group enlists the pianist Vicki Ray for a performance of Morton Feldman’s “Piano and String Quartet.” Tuesday’s program includes a premiere by Roscoe Mitchell, as well as modern masterpieces by Ruth Crawford Seeger and Ben Johnston encountered far too infrequently. At 8 p.m., Roulette, 509 Atlantic Avenue, near Third Avenue, Boerum Hill, Brooklyn, (917) 267-0363, roulette.org; $15, or $10 for students and 65+. (Smith)
Jenny Lin (Wednesday) This inventive pianist devotes her concert at the Stone to music written for dance — specifically, for Merce Cunningham and his company — by John Cage, David Behrman, John King, Stephan Moore, Christian Wolff and Gordon Mumma. At 8 p.m., the Stone, Avenue C and Second Street, East Village, thestonenyc.com; $10. (Kozinn)
