If "Sub/Super" was the sound of time liquefied, "lightdark" is time fossilized - gently exhumed with tweezers, brushed of its oxide crust, and held up to the light to see what shadows it casts. Portland’s Matthew Mercer, longtime builder of both dancefloor pulses and ambient hushes, now turns inward toward the sediment layers of his teenage self - cassette tapes forgotten in drawers, humming quietly in their plastic tombs for three decades until someone remembered to press rewind.

But don’t expect lo-fi charm or retro kitsch. "lightdark" is no VHS-core indulgence. It’s what happens when you treat adolescent tape hiss like a sacred text - one to be rewritten, remixed, and respectfully mistranslated through decades of lived experience and newer, weirder software.

There’s a kind of anti-narrative at play here. Each track feels like a footprint that’s already half-erased by wind, a gesture that never quite finishes. "Elutriation, Essentialization, Estrangement" sets the tone (and the syllabic bar) with flickers of half-tones that hover just above recognition. These aren’t melodies so much as events - sonic apparitions that appear in the periphery and disappear when you turn to face them.

"Scalare" and "Velvet Meridian" hang like thoughts you almost had, while "Neon Spire" and "Tangerine Glass Orchid" flirt with the shimmer of classic ambient but dissolve before they can bloom into something obvious. "Silver Whisper" lives up to its name, tracing a fragile outline in dust and delay. You get the sense that Mercer isn’t composing so much as conversing - with younger versions of himself, with rusted machines, with silence that once meant something and now means something else entirely.

What’s impressive isn’t just the aesthetic restraint - though Mercer has that in abundance - but the conceptual coherence. He’s not simply cleaning up old jams from his youth. He’s interrogating them, editing them like diary entries written in another language. The original tapes become collaborators, sometimes resisting, sometimes revealing, but never entirely yielding. It’s as if Mercer’s past self is peeking through a keyhole, not entirely sure if he should come out and say hello.

Where many artists use archival material as a springboard for maximalism, "lightdark" chooses subtraction, erosion, erasure. The title is no gimmick: this really is music that flickers at the edge of legibility, half in light, half in shadow. It's ambient music for those who trust silence more than resolution. Every track feels like it ends in an ellipsis.

This is ambient not as background, but as archaeology. "lightdark" doesn’t just drift - it decays, reforms, and questions its own shape. It's slow, not in tempo but in intention. Mercer asks you not to listen hard, but to listen softly, the way you might remember a dream while brushing your teeth. And just as dreams morph in the remembering, these tracks shift each time you revisit them - more mirror than map.
There’s a strange warmth beneath the spectral textures, like a memory of something that might never have happened. Or did. Or could. "Alabaster Blaze" glows faintly, like a candle under ice. "Oath Contour", the closer, sounds like a promise half-kept and fully mourned. The whole album has a kind of beautiful futility to it, like trying to press a leaf back onto the tree it fell from.

"lightdark" is an ambient detour with nowhere to be. A record that doesn’t build toward climax or catharsis, but instead wanders through liminal interiors, humming to itself in a language forgotten before it was learned. It’s as if Mercer took a shoebox full of sonic fossils, dusted them off with reverence, and then sculpted something new out of their shadows.

This is music for archivists, dreamers, listeners who understand that even hiss has a history. Don’t expect answers. Just expect to feel strangely seen by a version of yourself you’d almost forgotten.

And if that sounds too poetic, don’t worry - the tapes understand.
