In Seth Armstrong’s hands, Los Angeles is a city of light—and secrets. His latest exhibition, Subrosa, opening at Unit London, trades in illusion and intimacy, peeling back the city’s sun-drenched facades to reveal what breathes, burns, and waits just behind the hedges. These are not passive landscapes. These are oil-drenched confessions, framed in stucco and foliage.

Armstrong paints with the quiet precision of a voyeur who loves what he sees—even when it unsettles him. Windows glow, palm shadows stretch, and suburban streets whisper stories too large for the frame. And like the Latin phrase that gives the show its name, sub rosa—“under the rose,” or in secrecy—his paintings invite us into that liminal hush between knowing and merely noticing.

Painting a City in Mid-Sentence

Raised in L.A., trained in Northern Holland and the Bay Area, Armstrong is fluent in contradiction. He pairs the tactile romance of oil paint with the detached gaze of a documentarian. A bungalow isn’t just a home; it’s a mask. A window isn’t an aperture—it’s a dare.

Whether working in narrative portraiture or lush urban landscapes, Armstrong’s strength lies in the unresolved tension between beauty and unease. His palette is saturated, almost cinematic—blues that hum like twilight, yellows that radiate like memory. His compositions flirt with hyperrealism, yet resist slickness. The brushwork breathes. The surfaces carry time.

In Subrosa, that tension blooms. Houses sit behind wild tangles of greenery. Streets wind through sleepy foothills, basking in the golden hour. But there’s always something more—a figure glimpsed through a curtain, a scorched ridge in the background, a door left ajar. Each painting is a question: Who lives here, and what are they hiding?

The Intimacy of Observation

The works are rooted in Armstrong’s early-morning walks with his son—quiet explorations of his own Los Angeles neighborhood. There’s a father’s tenderness here, but also the curiosity of an artist attuned to shifts in light, shadow, and mood.

His Los Angeles is not the polished fantasy of postcards, but a tangle of domestic ritual and silent unrest. There are no Hollywood hills here, only human hillsides—teeming, breathing, and strangely still. In one work, a curtain billows but no one is seen. In another, a distant figure stands motionless in a kitchen window. You lean closer. The painting dares you to intrude.

Armstrong doesn’t hand us answers; he paints the possibility of stories.

Sometimes you get a peek inside, sometimes you don’t.

– He says.

Light, Smoke, and Memory

What gives Subrosa its staying power is Armstrong’s masterful manipulation of light—not just to illuminate, but to layer mood, narrative, and ambiguity. His canvases feel suspended between times of day and states of mind. The air is heavy with stillness, or smoke, or both. The past clings to every lawn, every stucco wall. Even the trees seem to remember something we’ve forgotten.

And yet, these paintings are never cynical. Armstrong paints with love—not sentimentality, but the kind of love that sees the flaws, the cracks, the mismatched curtains—and lingers anyway. His L.A. is wounded and wondrous. A place where myth and reality nestle under the same jacaranda tree.

The Art of Looking Again

In an age of speed-scroll and image saturation, Armstrong’s work insists on slow seeing. These are paintings that reward attention. That ask you to come closer. That offer surprises on the third, fourth, fifteenth glance.

They’re also remarkably democratic: anyone who’s walked a sidewalk at sunset, anyone who’s seen a porch light flick on in the dusk, anyone who’s lived inside or just outside someone else’s story will recognize something here. Not everyone knows oil paint, but everyone knows what it means to wonder what happens behind a window.

Ultimately, Subrosa is less a place than a sensation. A held breath. A half-known truth. In Armstrong’s hands, Los Angeles becomes an atmosphere of intimacy and ambiguity—a city forever between confession and concealment.

He doesn’t paint what we see. He paints how it feels to look.

And that is something worth lingering over.
