“The array of enormous sounds and hackle-raising textures on Phos combines the spontaneity of improvisation with the full potential of digital postproduction. The trio recorded the material live during one night in the studio, after which Cymerman and engineer Marc Urselli passed it back and forth, blowing it up and cutting it down. The results feel massive enough to generate their own gravity—especially when heard through headphones. On “Incantatory Sentience,” twanging strings and detonating beats circle around your head like a midnight dance enacted by blacked-out skyscrapers. “Corpuscular Refraction” is even less decorous, launching one blast after another, each more withering than the last. From start to finish, Phos sustains a black-on-black atmosphere illuminated only by the occasional spray of aerosolized crimson.”

Denovali is pleased to present Cycle and Reveal, the fourth full length LP of contemporary classical works by acclaimed composer Mario Diaz de Leon. Featuring bold performances by a cast of longtime collaborators, this compilation is an essential chapter in his celebrated series of recordings for acoustic instruments and electronics.
The A-side features two works written in early 2017, which colorfully embrace hypnotic repetition alongside dynamic contrasts and distinctly embody the electrifying post-minimalism that Diaz de Leon is known for. Opener Sacrament is written for a trio of musicians from Talea Ensemble and features the composer’s shimmering, bass heavy electronic production. This energetic piece, driven by the virtuosity of marimba player and Talea executive director Alex Lipowski, makes use of rapid-fire arpeggiations and heavy rhythmic unisons. These are starkly contrasted with moments of reverberant echo, bursts of noise in the flute and electronics, and ecstatic rhythms. Labrys, written for ICE bassoonist Rebekah Heller, builds on the celebrated legacy of solo + electronic works heard on his 2015 album The Soul is the Arena. Built around virtuosic interplay between bassoon and synthesizer, Labrys features shifting and hypnotic repetition alongside expansive melodies and sub-bass frequencies.
The B-side consists of two works composed in July of 2016 which draw from primal, incantatory, and improvisatory sonic landscapes. Irradiance, a collaboration with cellist Mariel Roberts, begins with a series of spacious riffs exploring the extremes of the cello’s register which transform into a climactic frenzy of noise loops. Tuning the cello’s low C down to a growling G, Roberts interpreted the sounds of each pre-recorded loop by ear. The piece gradually builds from cavernous depths into an ecstatic climax of anarchic noise. Concluding track Mysterium iswritten for the ICE trio of flutist and ensemble founder Claire Chase, clarinetist and artistic director emeritus Joshua Rubin, and bassoonist and current artistic director Rebekah Heller. Archaic melodies, improvised heterophony, spectral transformations, echoes of Klang-era Stockhausen, and the colorful noise of Moog and Ciat-Lonbarde synthesizers combine to create an expansive and wildly ritualistic atmosphere.
Cycle and Reveal was recorded in vivid detail by Marc Urselli (John Zorn, Laurie Anderson) at East Side Sound, Stephen McLaughlin at EMPAC, and mastered by Ryan Streber at Oktaven Audio. Diaz de Leon invited Melbourne-based visual artist Yuria Okamura to design the cover image and inner sleeve symbols. Sharing Diaz de Leon’s interest in the reinterpretation of religious art, Okamura’s cover “maps and reconfigures geometric patterns and symbols that reference esoteric symbolism, occult diagrams, religious architecture and decoration.”
Recording of Cycle and Reveal was supported by the Alice M. Ditson Fund of Columbia University.
“Mr. Diaz de Leon sells his vision with aplomb on a new album performed by the TAK Ensemble and the composer himself (on synthesizer, naturally). The edgy electronic timbres can serve a range of compositional functions: contrasting dramatically with the purity of a soprano’s sound, in one moment, before finding, in the bass clarinet, a partner in grain.”
-Seth Colter Walls, The New York Times
Sanctuary is the first album-length classical work by the NYC-based composer and performer Mario Diaz de Leon. It was written in collaboration with TAK Ensemble, a quintet devoted to energetic and virtuosic performances of contemporary music. Combining stark rhythms with ecstatic gestures, the piece embraces shifting repetition, shimmering harmonies, and elements of post-minimalism to dramatic and expansive effect.
Recording of Sanctuary was supported by the Alice M. Ditson Fund of Columbia University.
“Longtime readers may remember modern composer Mario Diaz de Leon from his solo experimental electronic project Oneirogen…Diaz de Leon’s musical ambitious extend beyond metal adjacent and into metal proper with his project Luminous Vault, a duo with bassist Sam Smith of Artificial Brain, which marries the pair’s mutual interest in brain-bending death metal and electronic music.”
-Joseph Schaefer, Invisible Oranges
“Dark, idiosyncratic, chasm-born black/death metal featuring one member of the excellent Artificial Brain. While the blackened elements are undeniable, it’s the mechanical surge-and-pull of Godflesh that appears to be the main driver here. From inexorable thrusts and dour synth passages a vast obsidian structure is built, around which tremolo-picked guitar lines flash like jagged forks of lightning.”
–Alex Deller, Collective Zine
“Convivium” is Mario Diaz de Leon’s third album under his ONEIROGEN alias, and follows the “Plenitude” EP, released in 2015. It was developed over a period of two and a half years, primarily through live performance in the metal and noise underground of NYC. Like its predecessor, the album’s core instrumentation is an array of hypnotic synthesizer riffs, pummeling percussion, distorted vocals, and surging noise. With “Convivum”, Diaz de Leon has crafted a powerful and singular work of heavy electronic music.
“Like the rest of Sheen, ‘Bare Arms, Black Dresses’ was edited and layered from hours of free improvisation, recorded and mixed by Jamie Saft. Over 10 minutes, its delayed guitar loops and midnight clarinet moans move from syrupy metallic drone to sputtering, gnashing noise, replete with guitar skronk that sounds like the garbled remains of a busted Autopsy live bootleg.”
– Lars Gotrich, National Public Radio
“Toby Driver and Mario Diaz de Leon bring experience as veterans of extreme rock, noise and classical music, and on Sheen both men make liberal music of electronic layering and distortion. Cymerman is right there with them. On ‘Singing Psalms,’ for example, his clarinet’s voice is first magnified, then pixilated, and then utterly blasted like a solar flare over strata of digital filth and laconic guitar figures.”
– Bill Meyer, Downbeat Magazine
“It seems like only yesterday that NY-based composer Mario Diaz de Leon issued The Soul is the Arena, a collection of three bold contemporary classical works. But as those acquainted with Diaz de Leon’s work well know, he also issues material of a dramatically different kind under the Oneirogen (o-NI-ro-jen) name. Plenitude, an EP-length, five-track prelude to an upcoming full-length, perpetuates the uncompromising sound design first explored on 2012’s Hypnos and then a year later on Kiasma. In the two years since its release, Diaz de Leon has further developed the project’s sound via live appearances in NYC’s underground metal and experimental scenes. The music’s overall intensity doesn’t declare itself immediately, as “Oxygen” inaugurates the EP with three minutes of restrained keyboard chords and slow-building ambient atmosphere. “Collapsing,” on the other hand, wastes little time at all in laying out its doom-laden soundworld when seething synth riffs and hammering salvos of percussion set the nightmarish scene and Diaz de Leon’s vocals—reminiscent of early Nine Inch nails, the words are more screamed than sung—plunge it into a caustic doom-metal zone. And with the singing so heavily distorted, one turns to the package’s inner sleeve to review lyrics rendered indecipherable by their delivery. Though it might seem hard to imagine, “Vessel” is heavier still, with the roar of the singing matched by the brutalizing instrumental design. The title track, thankfully, offers a welcome respite from such intensity in augmenting softly whispered vocals with a glacial synth backdrop, after which “Emergence,” in a nice framing gesture, echoes the instrumental design of the opener in unleashing a vibrant array of declamatory synth statements and portentous bass throbs.”
“The Soul Is the Arena is Diaz de Leon’s latest chamber-music album since Enter Houses Of, and it’s both shorter and more all-encompassing. In three different pieces that collectively stretch just over 40 minutes, he gives listeners two riff-rollercoaster duos and a 20-minute, chamber-band essay of grim, beguiling beauty. The opener, “Luciform”, is a duo between Diaz de Leon’s electronics and flutist Claire Chase (a recent MacArthur “Genius Grant” awardee). Over the course of its 13-and-a-half minutes, Chase’s flute sometimes often carries the melodic line, while the electronics swoop in big, sine-wave-surfing curves behind her. At other points, Chase’s breathy sound is just a complement to the rampaging crunch of the composer’s programming. The fast switches are what keep the piece interesting. The second duo piece is the album’s title track, and it asks for Joshua Rubin’s bass clarinet to go into reed-squawk mode. (Rubin manages this risky, awkward move with impressive grace.) Later on, the instrumentalist and the pre-engineered sounds partner up for a memorably precise and glitchy passage. The work packs a hell of a lot into nine-and-a-half minutes—so much so that you might need a little bit of a breather. Diaz de Leon has you covered on that count with the album-closing “Portals Before Dawn” (on which he plays synths alongside a sextet of instrumentalists from the International Contemporary Ensemble). The composer tried a similar strategy to close out Enter Houses Of, but this longer, more gradually surging and receding composition gets more out of the composer’s ambient fascinations. Diaz de Leon hasn’t put out an uninteresting release yet, but this compact and wide-ranging album is now the best introduction to his refined feel for instrumental extremity.”
-Seth Colter Walls, Pitchfork
“With Kiasma, the New York-based composer Mario Diaz de Leon brings an interesting twist to his Oneirogen project by amping up the metal elements included on his debut album Hypnos. In fact, the fifty-minute set takes no time at all in announcing that move when the full six minutes of the opening cut “Numina” are dominated by guitar distortion, shuddering six-string textures, and an overall death metal-styled sense of foreboding, desolation, and doom.
But Kiasma is far from one-dimensional, and that’s what makes it interesting. The second track, “Pathogen,” while featuring no shortage of molten guitar textures, counterbalances its metal leanings with sophisticated soundscape design of dark ambient character. Put simply, Oneirogen wisely balances the metal and electronic sides in a manner seldom attempted, and the effect proves to be arresting, especially when drums are wholly eschewed. The album is often epic and grandiose in tone, never more so than during pieces of intensity so great they verge on harrowing, such as “Mutilation” and the album’s centerpiece, “Katabasis,” which finds Oneirogen’s lethal chords lurching like some diseased monstrosity across blasted ruins for fourteen doom-drenched minutes. At album’s end, “Mortisomnia” changes things up by adding Mario Diaz de Leon’s vocal growl to the tune’s guitars-and-synths landscape.
Yes, Kiasma is heavy, of that there’s no doubt, but it’s also refreshingly different from the norm. It’s rare indeed to hear someone, as Oneirogen does, using multi-layered guitar shredding to craft nightmarish dark ambient set-pieces. Doom-laden material never sounded as musical as it does here.”
Further down the apocalyptic tunnel initiated on the LP “Hypnos”, these 3 tracks of dark illumination from Oneirogen (aka Mario Diaz de Leon) were composed as a counterpart to the full length. We find again his characteristic synth and noise used to harrowing effect, full of dramatic textural shifts, while bringing the metallic guitar and voice more to the forefront. Like Hypnos, the overall structure evokes a narrative, suggesting a descent into a hallucinogenic abyss, followed by a requiem-like emergence.
ONEIROGEN is Mario Diaz de Leon, a composer and multi-instrumentalist residing in NYC. “Hypnotic walls of shimmering sound” perhaps describe his aesthetic most broadly, whether his medium is electric guitar, electronics, or acoustic instruments. His influences include modern composition, underground metal, and noise electronics. “Hypnos” finds Diaz de Leon focused on his style of hallucinatory music. Far from being a follow up to 2009′s “Enter Houses Of” (a genre defying album of new classical works), “Hypnos“ is a new direction, merging ethereal synths, brutal distortion, noise, and dark ambient. The album takes its title from the Greek god of sleep (also closely associated with night, death, and dreaming), and the music itself is a wild and varied descent into the otherwordly, recasting familiar elements in a revelatory new light. On the opening and closing tracks, hyper fast synth tones create a rushing, cathedral –like atmosphere. Tracks such as “Consumed”, “Hypnocaust”, and “Kukulkan” feature psychedelic, crushing distortion as their primary focus, taking equal influence from doom metal, black metal, power electronics, new age music, and synth-based horror soundtracks. “Cinerum” and “Faithless” are highly structured takes on dark ambient, bringing the listener into haunting, strikingly beautiful realms of isolation, bleakness, and saturated noise textures.
“There are moments of artificial ethereality, where plasticized washes of synthetic sound recall the antiseptic calm of new age music, but they’re routinely upended by rapidly pulsing arpeggios, extreme lower-register growls, and rudely distorted, striated tones. Diaz de Leon nods to low-rent horror-film soundtracks (a la John Carpenter or Goblin) but also incorporates whiplashing bursts of power electronics and the ambience of doom metal—all of which wafts, rips, and splatters through these drifty instrumentals. “Faithless” opens like a Tangerine Dream outtake from Risky Business, then suddenly takes a satanic-sounding detour, only to return to a kind of weird calm, like a post-nightmare awakening. Diaz de Leon’s real accomplishment with Hypnos is the unexpected directions the pieces take—they hit you with one surprising shift after another, without ever sounding haphazard or goofy.”
-Peter Margasak, The Chicago Reader
“Electronics have been part of classical music since at least the 1930s, the conservative programming of most mainstream presenters notwithstanding, but aside from Iannis Xenakis I can’t think of a composer who’s pushed harsh noise like young New Yorker Mario Diaz de Leon (he also plays in an experimental metal band called Mirrorgate). On last year’s fantastic Enter Houses Of, he juxtaposes relatively conventional lines played by acoustic instruments—some of which are quite lovely—with abstract electronic sounds that can be confrontational, even brutal. On “Mansion” the gracefully twining alto flutes of Claire Chase and Eric Lamb are surrounded by sputtering low-frequency digital pulses, haunting waves of ambience, lacerating bursts of synthetic shrieking, and explosive drumming by Nathan Davis that alternates between ceremonial gravitas and psych-rock fury. On “The Flesh Needs Fire,” Chase and clarinetist Joshua Rubin engage in swooping, acrobatic interplay while electronic noise builds in force, density, and nastiness. Diaz de Leon’s writing for acoustic instruments tempers dissonance with flashes of serenity, and his rhythmic sensibility likewise balances frenetic intensity with near stillness. The electronic element of his music is much more than merely decorative—it’s fully integrated, and alternately jostles, caresses, and dominates the other voices.”
