When you’re in the reviewing game long enough, it feels like you’ve seen it all. We’re within days of my third anniversary writing for The Progressive Subway, and 2025 feels like a wasteland. The blog is depressed by the lack of good new releases, the usual summer lull is hitting harder than ever, and I’m sifting through everything that’s available to review without enthusiasm. Insipid trad prog? No thanks. Uninspired prog rock? Not on your life. Middling djent debut? God, please smite me down. Sometimes you just feel that new releases no longer inspire you the way they did when you were a wide-eyed young reviewer with enthusiasm and hopes and dreams. If I employed a compass to point me to the interesting new releases, where would it take me?

Perhaps to Spaniard at large in the land of the ice and snow, Mario Infantes, formerly of baroque metal group Cult of Lilith, who has returned with a second solo effort, Bitácora (from the Spanish for binnacle: the casing for a ship’s compass). Exploring a range of moods and genres, Infantes melds a wealth of folk traditions with metal and symphonic influences, exploiting an ensemble of instruments from various countries in the process. The resulting concoction bears resemblances to his alma mater group, as well as the work of Igorrr, but utilises a rather different sonic palette. Singing in both Spanish and English (and quite possibly in other languages), Infantes leads the project as a multi-voiced, multilingual, multi-instrumentalist. He has a natural, operatic tendency, from Einar Solbergian high falsetto to resounding tenor, utilising Igorrr-esque harshes, layered choral harmonies, throat-singing (or close to it), and some more performative voice acting—moments of laughing, spoken word, even something akin to rap.

The instrumental bed, meanwhile, is a deft blend of metal instrumentation and folk instruments from around the world. Handpan features heavily, forming a raindrop dressing for the contemplation of ballad “Streams” and the Balkan lament “Notre Prison”, while a dissonant chiming gamelan underpins “Xhadhamtje”. At various other junctures, we hear from duduk (an Armenian double-reeded woodwind), bansuri (Indian bamboo flute), oud (Middle Eastern lute), zurna (double-reeded woodwind)¹, and doubtless more that my untrained ear failed to pick out. When the riffs come, they often have a rather loose structure, allowing Infantes to use them as an emphatic texture rather than as a restrictive rhythm that hampers the madness of his sonic science, perhaps best heard on “Cianuro”, where the riffs constantly morph, rarely repeating a measure. The resulting concoction is international yet seamless; while a particular section might sound Indonesian or Spanish or Eastern European, the totality seems borderless, the creation of a citizen of nothing smaller than the world itself. 

“Xhadhamtje” is probably the most avant-garde swing on the album with Infantes’ throaty keening and a palimpsest of sinister whispers and nightmare sounds ala Ecophony Rinne, giving way to an enormous operatic crescendo with help from shrieking guest vocalist, Stirga, and an eruption into metal riffs, all underpinned by a nightmarish windchime motif. “Muharib Alqifaar” opens with zurna, Phrygian wails and mysterious oud picking, before exploding into heavier and heavier riffs, and while the coda of Spanish rap feels tacked on, it’s mostly a very successful journey through Bitácora’s various modes. Closing epic, “Cianuro”, operates similarly: a nine-minute distillation of Infantes’ various idiosyncrasies, from balladic crooning sections to upsurges of manic metal. In these heavier moments, the guitar tone and prominence of the bass in the mix, as well as some of the operatic tendencies and manic harshes, have more than a whiff of Igorrr about them, but Infantes owns his sound for himself.

Indeed, it’s in his restraint that this is most apparent: “Sírenu” largely consists of Infantes and an oud with strings before its orchestral crescendo and a gorgeous guest performance from Sunna Friðjónsdóttir. “Away” relies heavily on handpan, much like “Streams” before it, growing inexorably toward a cathartically rhythmic, ritualistic chant. “Streams” is probably the most accessible track on the album, the swelling strings in its chorus proving genuinely stirring. Infantes excels at giving each track a distinct personality of its own, and intersperses the more experimental and heavy sojourns with calming palate cleansers; the softer moments are, perhaps, the album highlight, their meditativeness and sublimity proving a soothing palliative. 

As Bitácora closes with its conclusive coda of lo-fi flamenco and scatting, it’s hard not to feel like you’ve just returned from some astrally projected existential journey and come to at the corner table of a Spanish bar; after such a unique sonic adventure, it feels necessary to sit contemplatively for a minute or two. Certainly, Infantes is a remarkable musician and composer. And while the avant-garde scene can be demanding, and not every swing here lands, far more hit the mark than in the average work of this genre. Far too often, experimental composers throw everything at the wall to see what sticks, leaving listeners with an all too disjointed affair. But Bitácora manages that rare thing: an evocative, flowing listen with peaks and valleys, genuine emotion, and moments like a sonic punch in the face. A much-needed reminder that there are always innovative artists plugging away at their craft, and it’s nice when the compass leads you straight to them.
