What happens when you pair a double bass that seems to groan under the weight of centuries and a saxophone that breathes like a ghost trapped in the present? You get "Les herbages d’acier et d’émeraude", the debut duo release from Alex Reviriego and Tom Chant - a sprawling, raw, and unexpectedly intimate exercise in free improvisation.

Recorded in a single, unplanned session during leftover studio time, this album captures what can only be described as a séance of sound. Alex Reviriego’s double bass doesn’t just hum or bow; it scrapes, creaks, and moans like an ancient tree bent by the wind. Meanwhile, Tom Chant’s saxophone is equally unorthodox, whispering, shrieking, and splintering into fragmented utterances that feel less like notes and more like incantations.

The first track, "Des prés de flammes", sets the tone: long, sinuous tones from Reviriego’s bass create an earthy, guttural foundation, while Chant’s saxophone soars and sputters, as if unsure whether to console or antagonize. It’s evocative of John Butcher’s microscopic sax explorations, but with a looser, more restless energy.

From there, the duo pushes into darker, more visceral territory. "bondissent" is a tense dance of near-silence and sudden eruptions, with textures recalling the jagged improvisations of Evan Parker or Barry Guy. "jusqu’au sommet" takes things to another level, with Chant delivering some of his most aggressive playing on the record, his saxophone teetering on the edge of disintegration.

The album’s title, "Les herbages d’acier et d’émeraude" ("The pastures of steel and emerald"), along with its track names, draws from Rimbaud’s "Une saison en enfer" ("A Season in Hell"). This literary connection feels more than skin-deep. Just as Rimbaud shattered poetic conventions, Reviriego and Chant dismantle musical expectations, creating what Reviriego aptly describes as “profoundly imperfect and strange” music.

But imperfection is where this album thrives. Like the craggy landscapes of free jazz’s forebears, from Albert Ayler to Peter Brötzmann, the cracks and fissures in the music reveal its essence. It’s not about virtuosity or polish - it’s about capturing raw moments of connection and catharsis.

Reviriego’s liner notes reveal not only a shared artistic vision but also a deep personal connection between the two musicians. Their decade-long collaboration has culminated in this distilled exchange of ideas, where the boundaries between individual contributions blur into a single, shared voice.

For Reviriego, Chant isn’t just a collaborator; he’s a provocateur and a muse, someone who challenges him to reimagine what music - and perhaps life itself - can be. And for Chant, whose career has spanned decades and collaborations with improvisational titans like Eddie Prévost and Otomo Yoshihide, this album feels like a space where experimentation and vulnerability coexist in perfect harmony.

Trying to classify this album is a fool’s errand. Yes, it’s free improvisation, but it also flirts with noise, minimalism, and even a kind of broken-down chamber music. Comparisons to AMM or the Spontaneous Music Ensemble might come to mind, but "Les herbages d’acier et d’émeraude" is wilder, more untamed - a field of steel and emerald, indeed.

One of the most striking aspects of this album is its physicality. You can feel the exhaustion in the playing - the way the bow drags just a little longer, the way the breath falters but presses on. It’s not a slick studio product; it’s a document of two musicians pouring themselves into their instruments until there’s nothing left.

In this way, it’s almost the anti-album: unedited, unpolished, and unapologetically human. And yet, it’s precisely this rawness that makes it so compelling. It’s a reminder that sometimes, music doesn’t need to be perfect; it just needs to be real.
