In Disobedient Spaces, at Columbia University’s Wallach Art Gallery, Rosenfeld’s “+s” repeat throughout the show. Her actions—whether alone or with the collective she co-founded, Colectivo Acciones de Arte (CADA)—often took place in the contested, militarized space of the street.

[See] [Saw] [Sound] [Wave] at Fall River Museum of Contemporary Art (FR MoCA) features the work of historic and contemporary artists interested in the acoustic properties of space. It includes recorded works by Alvin Lucier, Pauline Oliveros, and Laurie Spiegel, a sound installation by Erik DeLuca, and lithographs and sound-dampening, wall-mounted textile panels by Aviva Silverman. The physical space of the gallery is largely blank, enabling auditory information to replace visual information.

At Arts and Letters, Wadada Leo Smith and Raven Chacon both present an expanded understanding of what a score can be and do.
