INTERNATIONAL CONTEMPORARY ENSEMBLE at Abrons Arts Center (April 28, 8:30 p.m.; April 29, 8 p.m.). Enjoy ICE all weekend long with a festival of free concerts that ranges over contemporary music with abandon. On Friday, there’s a collaboration with the French ensemble L’Itinéraire, featuring music by Pauline Oliveros, Francesca Verunelli and others; on Saturday, a preview of new creations by Wojtek Blecharz.
‘MADRIGAL OPERA’ at National Sawdust (April 28-29, 7 p.m.). The Philip Glass celebrations continue unabated, now with a rarity: a 1980 chamber opera left deliberately abstract, for later directors to complete. R. B. Schlather, one of our more ambitious and effective younger directors, takes up the task. The violinist Johnny Gandelsman, the violist William Frampton and the voices of Choral Chameleon are the performers.
WALL-TO-WALL STEVE REICH at Symphony Space (April 30; 3, 5:30 and 8 p.m.). Eight hours — yes, eight hours — of Steve Reich at another round of birthday celebrations for the composer, and with quite the lineup. There are three concerts, with barely a pause for breath: Among other performances, catch Vicky Chow in “Piano Counterpoint” and the Mivos Quartet in “WTC 9/11” at 3 p.m.; the marvelous ensemble Alarm Will Sound in “Four Genesis Settings” and “Radio Rewrite” at 5:30; and “The Desert Music” from the American Composers Orchestra at 8. Crucial music, by crucial performers — and all for free.
