DARMSTADT at Le Poisson Rouge (Feb. 20, 8 p.m.). This will be the 15th annual performance by this Brooklyn group of Terry Riley’s “In C,” that classic early statement of Minimalism. Among the notable performers this year are Gelsey Bell and Joan La Barbara.

MARCO FUSI AND THE KUKURUZ QUARTET at the Italian Academy (Feb. 20, 7 p.m.). This quartet — pianos, not strings — is joined by a leading new-music violinist for a sprawling, free program that culminates with another contribution to the Julius Eastman revival, a performance of his “Gay Guerrilla.” Before that, there is music by Salvatore Sciarrino, Giacinto Scelsi, John Cage and Marcel Zaes.

WANG LU at Miller Theater (Feb. 21, 8 p.m.). This Chinese-born composer benefits from the first of Miller’s spring composer portraits, and from the advocacy of the new-music royalty on hand to perform her pieces: the International Contemporary Ensemble and Yarn/Wire. There’s one world premiere, “A-PPA-Aratus,” as well as “Childhood Amnesia,” “Rates of Extinction,” “Urban Inventory” and “Siren Song.”
