Robert Ashley Operas (Saturday and Sunday) The composer Robert Ashley, who died in March at 83, attracted acclaim for his imaginative, unconventional operas that meshed spoken dialogue and experimental idioms. The Whitney Biennial concludes its celebration (which has included the premiere of his opera “Crash” and a Spanish language version of “Perfect Lives”) with “The Trial of Anne Opie Wehrer and Unknown Accomplices for Crimes Against Humanity,” a 1968 work that Mr. Ashley called a “speaking opera.” At 2 p.m., Whitney Museum of American Art, 212-570-7766, whitney.org; $20, $15 for students and 65+.

Collected Stories (Saturday, Sunday and Tuesday) The final three nights that the composer David Lang has programmed as part of this series tied to his residency at Carnegie Hall are characteristically wide-ranging. On Saturday the pianist Louis Lortie, a Liszt specialist, performs in a single evening that composer’s profound three-hour cycle “Années de Pèlerinage” (“Years of Pilgrimage”). Younger composers have their day on Sunday, with new and recent works by Kaki King, Kate Moore, Richard Ayres and Donnacha Dennehy performed by the ensemble Alarm Will Sound and soloists like the soprano Kiera Duffy. The program on Tuesday begins with two works by John Cage, “Indeterminacy” and “27’10.554,” performed simultaneously, and continues with the premiere of Mr. Lang’s “mystery sonatas,” composed for the brilliant young violinist Augustin Hadelich. At 6 p.m., Zankel Hall, Carnegie Hall, 212-247-7800, carnegiehall.org; $34 and $40. (Zachary Woolfe)

On the program are Ligeti’s “Musica Ricercata” and Six Bagatelles for Wind Quintet, Birtwistle’s “Cortege,” George Benjamin’s “Viola, Viola” and Andy Akiho’s “Ligneous 1,” as well as the Ricercar from Bach’s “Musical Offering.” At 2:30 p.m., SubCulture: Arts Underground, 45 Bleecker Street, near Lafayette Street, East Village, 212-533-5470, subculturenewyork.com; $15 in advance, $20 day of show.

FLUX Quartet (Saturday) For fans of both beauty and endurance, few events in music can surpass a live performance of Morton Feldman’s sublime, glacial String Quartet No. 2, which lasts more than six unbroken hours. This ambitious quartet has, improbably enough, made something of a specialty of it, and are now bringing it to the intimate, newly renovated Board of Officers Room at the Park Avenue Armory. At 3 p.m., Park Avenue Armory, 643 Park Avenue, at 67th Street, 212-933-5812, armoryonpark.org; $40. (Woolfe)
