Art audiences love experiential art (witness long lines at every Yayoi Kusama walk-in sculpture, the Rain Room, etc), so it’s somewhat surprising how few painters offer to envelop viewers in their work. Sarah Cain is not one of the reticent artists, however. Her installation, Dark Matter, at Chelsea’s Galerie Lelong covers the gallery floor in bold patterns on lino, competing with but also complimenting vibrant canvases that employ beads, pinwheels, string and more to take the composition off the canvas.
