App's painting "Mayday" loosely relates to the May 4, 1970 massacre of students at Kent State University, where he was finishing his undergraduate studies at the time. This is not a festive Mayday. The deep space in the painting is gray, or gray with a touch of greenish tinge. Ten crisp red, gray-blue, and mustard stripes crisscross the surface of the painting. At the front are four red stripes: They're vertical and insistent and, App says, stand in as surrogates for the four students killed by the National Guard at Kent State. Behind the red, in the middle, on the horizontal, are the thickest stripes. These three gray-blue stripes are blunt and solid. Three vertical mustard stripes stand behind the blue and against the deep gray. The mustard stripes are sentinels in a Mayday corps. "Mayday" is a close view of a formidable barred window. There is nowhere safe in this Mayday, nowhere outside or inside, nowhere safe in the middle. "Mayday" is a danger sign, a call for help.
