In “Radio Grow,” her NYC solo debut, the young Philadelphia painter Sarah Gamble makes meaty paintings of electromagnetic particles shimmering the spectrum of color and light through darkly brooding landscapes.

They are radio waves of pop songs and microwaved newsflashes and cell phone love chats, making their way with ectoplasmic vitality into the atmospheric flesh of the hills. They are not quite defined but very specific, with the darkly lyrical emotional intensity of Giorgione’s Tempest.
