Starting from the premise that art is a concept, many post war artists have stripped aesthetics from their work and found the minimal path necessary to convey their message. Artists have accomplished this by working with neon. We will look at works of important artists that have mastered the medium of neon to convey emotion and ideas and thereby expanded the definition of what constitutes art. Practitioners to be studied include Yael Bartana, Glenn Ligon, James Clar, Dan Flavin, Tracey Emin, Ivan Navarro, Bruce Nauman, Lori Hersberger, Jung Lee, and others. We will explore how these artists have pushed the boundaries of art and the neon medium.
