Classical Music in NYC This Week

ERIC HUEBNER AND STEVEN BECK at Miller Theater (Jan. 23, 6 p.m.). The first of this winter’s pop-up concerts in Morningside Heights, where the audience sits on the stage and has easy access to beer, is a double-piano feast: Ligeti’s “Three Pieces for Two Pianos,” Steve Reich’s “Piano Phase” and, dauntingly, Pierre Boulez’s “Structures I.”

FOCUS! FESTIVAL at Peter Jay Sharp Theater (Jan. 19, 7:30 p.m.). For this year’s Juilliard festival, director Joel Sachs has chosen to showcase composers living and working in China, with one honorable exception. This first of six free programs, which conclude on Jan. 26 with the Juilliard Orchestra proper, sees the New Juilliard Ensemble play two world premieres, from Wang Shuci and Liu Sola, plus music by Ye Xiaogang and that one interloper, Chou Wen-Chung, a student of Martinu’s and Varèse’s who has lived for decades in New York.

JULIUS EASTMAN at The Kitchen (Jan. 25, 8 p.m.). Any retrospective for this composer, who died in 1990 but whose music is having a renaissance, is a welcome one. A thoughtfully constructed project at this Chelsea space, complete with an exhibition of archival material, is particularly so. On this program, two works from 1974, “Joy Boy” and “Femenine,” both played by a group that Eastman had a close relationship with, the S.E.M. Ensemble, under the direction of Petr Kotik. Other events run through Feb. 10.
