The paintings of Lewis Hammond, a young British artist of Afro-Caribbean descent, combine earth tones—dark reds, muted browns, and maroon beiges—to suggest shadow, strangeness, and stillness. It comes as no surprise that Hammond’s moody and sometimes horror-tinged style has been likened to that of Goya, as well as to William Blake’s demonic visions. A series of paintings conceived in pre-quarantine Mexico and en pleine crise in London is on display. —E.C.
