One striking, insightful, precarious pairing follows another in this frankly incredible group of paintings that Salle has managed to call in. Red stippling in a recent Walter Price echoes the gray atmosphere of an Edgar Degas; abstraction by Amy Sillman looks like a color negative of Albert Oehlen’s, or vice versa; and Martha Diamond, Willem de Kooning and Brice Marden all use wavering, expressive lines — to very different effects, if you think of their individual contexts, but as mere variations on a theme when they’re side by side.
