We did an interview with Karapetian explaining and discussing her work in general and these pieces specifically.
Princeton grad, Sheinkman, creates coiling black and white lines in his work (be they drawings or paintings). This pieces is oil, alkyd and graphite on linen.
Breuer has been exhibiting his work for over 20 years. He is a photographer but not your typical "point and shoot" sort of photographer. He creates doing what some might consider "misusing" materials. He burns photopaper, scrapes it and otherwise abuses it. He creates interesting chromogenic works, photograms, silkscreens and more.
