David Greilsammer (Tuesday) The brilliant pianist David Greilsammer, who is also a conductor, has a gift for devising programs and recordings that juxtapose old and new music. His latest Sony Classics recording alternates Baroque keyboard sonatas by Domenico Scarlatti with sonatas from Cage’s Sonatas and Interludes for Prepared Piano. Mr. Greilsammer will play the entire program from this exciting album at Le Poisson Rouge, on two pianos, naturally, one for the Scarlatti, another “prepared” with bolts, clips and such in the strings, for the Cage. At 7:30 p.m., 158 Bleecker Street, near Thompson Street, Greenwich Village, 212-505-3474, lepoissonrouge.com; $15 to $25. (Tommasini)
International Contemporary Ensemble (Saturday and Sunday) This excellent new-music ensemble contributes to the Whitney Biennial with a program dedicated to Pauline Oliveros, whose works explore the sonic possibilities of noise and sound — an aesthetic she fosters with her Deep Listening Institute. International Contemporary Ensemble will present some of Ms. Oliveros’s “Text Scores” on Saturday, and the two will perform together on Sunday, with the composer playing the accordion. Listeners can enter Ms. Oliveros’s sound world before and after the concert in the Deep Listening Room — which processes and plays back the sounds of the Whitney lobby. Saturday at noon; Sunday at 4 p.m., Whitney Museum of American Art, 212-570-7766, whitney.org; $20, $16 for students and 65+. (Schweitzer)
Locrian Chamber Players (Thursday) No program notes, preconcert discussions or music “less than a decade old” are the hallmarks of this chamber group, which here performs the premiere of Nils Vigeland’s “Capriccio,” and new works by Ashley Wang and Edmund Jolliffe. George Crumb’s “Sun and Shadow,” Harrison Birtwistle’s “Lied” and Justin Merritt’s “A Gauze of Misted Silver” round out the program. At 8 p.m., Riverside Church, 10th floor performance space, Riverside Drive at 122nd Street, Morningside Heights, locrian.org; free. (da Fonseca-Wollheim)
