Sam Gilliam, “Starting: Works on Paper, 1967-1970,” and Chris Martin, “The Eighties,” at David Kordansky Gallery. Kordansky is pulling together a series of never-before-seen works on paper by Gilliam, the Washington, D.C.-based abstract artist known for making painting sculptural: draping canvas in galleries, or mounting his canvases onto beveled frames. This includes some of his earliest experiments, from the 1960s: folded pieces, expressionist pieces and works with calligraphic inks and light washes. Also on view is a show of paintings by New York artist Chris Martin, reflecting a moment of transition for the artist during the 1980s. Through April 27. 5130 W. Edgewood Place, Mid-Wilshire, Los Angeles, davidkordanskygallery.com.
