“The line bore its own diacritical mark inside itself as a tendency for waywardness. Line [is] always about to go off like an unheld note,” writes Fred Moten in an introduction to Gladman’s 2020 book of drawings One Long Black Sentence. And indeed, Gladman’s lines are sustained errantry, ambling in all directions and none. Her drawn writings stretch on and on, and her pen sustains uninterrupted contact with the page for what feels like hours, feeding off of its own circuit of energy without pausing for breath.
