The self-taught Belgian artist Raoul De Keyser (1930–2012) was known for his unpretentious watercolors and oil paintings. Using simple shapes and subtle shifts of color in works both visually intense yet noticeably spare, De Keyser quietly explored the vanishing point between representation and abstraction. As was said of him in 2004, during a retrospective at Whitechapel Gallery, “he reconciles the irreconcilable.” The first De Keyser exhibition in Greater China presents works from his last 25 years, accompanied by the online exhibition “New Visions.” —E.C.
