Contributed by Katy Crowe / The German noun Umwelt means environment. “ultraUMWELT,” the title of Rosy Keyser’s current solo show at Parrasch Heijnen Gallery, denotes a world of dynamically connected matter.

Her work recalls biomorphic/organic abstraction, but the serendipity her process allows gives her paintings bracing and distinctive freshness.
