Rubinstein's artwork focuses on the connection between the visual arts, music, text and film. It was last represented in a one-person exhibition at Phil Space Gallery in Santa Fe, New Mexico, November/December, 2015. Earlier pieces, such as Sky Shudder, Variation1, incorporate drawing, painting, original score, and text, into "a swirl of enigmatic composition."
Rubinstein, who may be better known as a composer and songwriter, has been drawing and painting for years, though only began exhibiting consistently in the past ten. The work has been exhibited at, or resides in, the collections of The Museum of Modern Art; The Whitney Museum of American Art; The Scottsdale Museum of Contemporary Art; The Fabric Workshop and Museum, The City of Albuquerque; The Lively Group, NYC, and in private collections around the world.
Rubinstein is a 2014 Rauschenberg Foundation Fellow and was in residence at The Rauschenberg Foundation, Captiva Florida, in February/March 2014. The award is given via nomination.
