Listening to Archipiélago feels like setting sail into a sea that both reflects and devours the sky - it’s beautiful, abstract, uneasy, and strangely alive. Sergio Merce, known as a saxophonist and sound artist based in Buenos Aires, brings his radically modified microtonal sax to the forefront, crafting a sonic landscape where harmony drifts slowly, as though caught in a long tidal breath.

Merce’s self-built alto sax is not a traditional instrument anymore: by reworking its mechanisms, he unlocks vast harmonic worlds. On Archipiélago, he extends that journey, using microtonality as a cartographic tool, drawing contours not just in pitch but in perception. The result is terrain that feels at once familiar and alien - like memory filtered through fog.

The album unfolds in four movements, but really in two long ones (“Marea” and “Un faro”) plus their smaller counterparts. The opening track, Marea (which means “tide”), is a nearly 24-minute ebb-and-flow of pitch and silence. Merce’s tone seems to stretch outward, then fold in on itself, creating swells of sound that feel as organic and inevitable as water quietly reclaiming the shore. It’s slow-motion wave poetry: abstract, but you sense the weight of something deeply grounded - maybe fear, maybe longing, maybe both.

Then Un faro (“A Lighthouse”) arrives, roughly fifteen minutes long, and the metaphor becomes more concrete. The saxophone’s microtonal shifts feel like a beacon shining in darkness, guiding a fragile vessel. This piece carries a kind of spiritual calm - not resignation, exactly, but the sort of alert peace that comes with knowing how far you have traveled.

Merce’s own words haunt the project: “disappearing into the silence, we seek to understand fear and suffering… sometimes sound becomes silence”. This is not music for easy listening; it is a meditation. And yet, it is not aimless. Every subtle flicker in tone, every hesitated breath of air, feels intentional, as though Merce is mapping emotional terrain we didn’t know existed.

Part of what makes this work so compelling is Merce’s dual identity as both craftsman and composer. His microtonal sax isn’t just a tool - it’s a collaborator. He plays it, yes, but he also listens to what it offers him, letting its internal harmonics speak back, guiding his improvisations. That dynamic makes Archipiélago feel less like a concert and more like a conversation - with yourself, with your fears, with the uncharted depths of sound.

Another important contribution is the mastering by David Sylvian, whose touch brings every nuance forward without smoothing away the rough edges. It’s a masterful balance: the recording feels intimate, yet cavernous. You hear the sax’s vibrations as clearly as you sense the space around them.

What Merce achieves on Archipiélago is less a resolution than a kind of ongoing pilgrimage: a sonic archipelago where each island is a shade of feeling, each gap between sounds a channel, and each return a moment of recognition. For listeners willing to surrender to its slow currents, the album offers not just textures but a way to see into sound - and perhaps beyond it.
