Aspen Edities News

Aspen is very proud to introduce ‘Non Sonett’ by the Christian Wallumrød Ensemble. This ensemble is a pioneering Norwegian chamber group whose work on ECM and Hubro has redefined the boundaries between jazz, contemporary composition and folk music.Across seven albums, the ensemble has developed a highly distinctive l anguage built on restraint, timbral nuance and collective interplay, placing it among the most influential European ensembles of the 21st century.

Bringing together some of the finest musicians in Norway, the ensemble draws on a rare collective sensitivity, where each player contributes to a deeply integrated and texturally rich sound world.

With Non Sonett, the Christian Wallumrød Ensemble opens a new chapter that grows directly out of recent years of work in more solitary and cross-disciplinary contexts. In this period, Wallumrød has developed material for solo performance as well as for dance, allowing ideas to take shape in more fluid and exploratory formats. Some of this material now finds its way into the ensemble, where it is met by the possibilities offered by instrumentation, collective playing, and the distinct voices of the musicians. At the same time, older pieces—originating in entirely different settings— re-emerge here in new forms, reshaped by the ensemble context.

A defining aspect of Non Sonett is the way many of the pieces function less as fully determined compositions and more as open frameworks: starting points, suggestions, or “springboards” for music. These structures invite response rather than prescribe outcome, relying on the ensemble’s inherent sensitivity and capacity to realize and transform the material in performance. The result is music that feels both precise and fluid, shaped in equal measure by composition and by the interpretative presence of the players.

Central to this album is a continued deepening of Wallumrød’s long-standing interest in ambiguity and in dissolving boundaries between different musical elements and expressive worlds. By placing contrasting materials and associations side by side—sometimes subtly, sometimes more overtly—the music opens up spaces where meanings remain fluid and interconnected. On Non Sonett, this approach is taken a step further, allowing these juxtapositions to play an even more active role in shaping the music’s character and flow.

This approach connects closely with the ensemble’s broader artistic trajectory. Over time, the Christian Wallumrød Ensemble has developed a language that is immediately recognizable—marked by reduction, clarity and a deep attention to sonic detail. While each release has its own character, the underlying aesthetic remains consistent: a focus on the inner life of sound itself. Rather than foregrounding gesture or virtuosity, the music draws the listener toward the smallest elements, where meaning emerges gradually through texture, spacing and timbre.

The listening experience becomes one of concentration and proximity, where each sound carries weight, and the accumulation of detail forms a larger whole. References may be sensed—to early polyphonic music, Norwegian folk traditions, or more recent experimental practices—but these are absorbed into a singular musical language that resists categorization.

As with the ensemble’s recent work, Non Sonett also continues the integration of electronics as a fundamental part of the sound world. Each musician engages with electronic elements alongside their acoustic instruments, creating a layered and dynamic sonic environment. At times, this leads into extended, exploratory passages reminiscent of analogue musique concrète; at others, electronics operate almost imperceptibly, subtly altering and extending the acoustic textures in real time.

Aspen Edities is pleased to present Aerial, the third album of the experimental quartet Oker.

Whereas their album debut Husene våre er museer (2018) and its follow-up Susurrus (2021) focused on collective and individual compositions, Aerial features two longform pieces of fully improvised music, sculpted from the recognizable acoustic sound palette that the quartet has developed across a decade of extensive touring. The titles, Aerial, Equinoctial Tide and Crepuscular Rays refer to meteorological and planetary phenomena, and in Oker’s interplay we hear light, wind, clouds, and tidal cycles transpire as shimmering, roaring, rubbing, coalescing and diverging environments of sound. The sonic stoicism and minimalism in their expression is challenged by frictioning micro-chaoses, combining to create calm, winding paths of musical detail and form. Echoing our planet and its meteorological reality, Aerial yields both consistency and perpetual change.

Bringing together some of the most compelling musicians from the Norwegian improvised music scene, Oker operates as an acoustic experimental quartet devoted to the amalgamation of improvised and composed modes of expression. Their music combines fine-tuned tonalities, deconstructed grooves, acoustic noise and other sonic events, taking their rather conventional instrumentation as a point of departure. Textures in gradual change coexisting with responsive and spontaneous gestures create a varied but coherent musical ecosystem which can be airy or dense, dry or blooming. A certain minimalist or stoic approach to sound production is an overarching and recurring element in all of Oker’s music, differentiating their sound from the majority of music in the field of improvised music or free jazz.

Acclaimed Belgian duo Poor Isa - comprising banjoists Ruben Machtelinckx and Frederik Leroux - returns with their third album, marking a significant evolution in their musical journey. Departing from their established duo format, this release introduces collaborations with two luminaries of the improvisational music scene: British saxophonist Evan Parker and Norwegian percussionist Ingar Zach. Known for their minimalist aesthetic, characterized by prepared banjos, Poor Isa continues to explore these textures while blending traditional and experimental approaches.

Evan Parker, a pivotal figure in European free improvisation, brings his distinctive soprano and tenor saxophone sound to the collaboration. Renowned for pioneering extended techniques, Parker's dynamic and energetic improvisations introduce a compelling contrast to Poor Isa's introspective sound world.

Ingar Zach contributes his innovative percussion work, using the Gran Cassa and vibrating speakers to create resonant textures. His approach adds depth and color, enhancing the album's exploratory nature.

Poor Isa provides a flexible framework, allowing Parker and Zach to imprint their unique voices while maintaining the duo's core identity.

Recorded at the legendary Atlantis Studio in Stockholm, Words Were Coming Out Our Ears captures a unique musical encounter in the moment. Pianist Johan Graden, bassists Vilhelm Bromander and Pär Ola Landin, and drummer Nils Agnas entered the studio without a fixed plan – the music emerged organically through improvisation and attentive interplay.

What sets this album apart is the instrumentation. With two double bass players, the music gains an unusual depth and weight, where the bass not only supports the harmony but also takes on melodic and textural roles. This is no traditional piano trio – rather, it's an ensemble where roles shift constantly, and the sonic landscape is shaped by sensitivity and openness.

One track features additional layers of sound with guest musicians Katarina Agnas on contrabassoon and Emil Strandberg on trumpet.

With Words Were Coming Out Our Ears, the ambition is to create a cohesive sonic identity – to allow each piece to take its own shape while still belonging to a unified whole. The music invites deep listening, guided by intuition and presence in the moment.

I envision this music as emanating from a moon inhabited by otherworldly life forms and ecosystems; these sounds as evoking the moon’s topographies, beings, lunar rivers, and strands of light — as if this moon’s essence were itself sonic, vibrational matter.

Musically and acoustically, Strands Of Lunar Light departs from a set of tones corresponding to a confined harmonic series segment of a very low fundamental frequency: 5.15 hertz. Through twelve continuous sections, each employing various methods of activating openly tuned guitar strings, the music is sculpted from the twenty-four pitches corresponding to harmonics 24 through 47 of this fundamental frequency.

At times, the natural second (octave) harmonics of the open strings are activated and introduce a secondary, octave transposed version of the original harmonic series segment, doubling the fundamental frequency to 10.30 hertz, and thereby revealing a brighter vibrational realm.

As a consequence of the rational pitch relationships integral to harmonic series of tones, these two sub-audio fundamental frequencies (pitch wise existing two and three octaves below the E-string of a double bass, respectively) can be heard in the music as the frequencies of the interference patterns produced by the simultaneous sounding of any pair of adjacent tones in the respective sets of tones.

These interference patterns, of 5.15 or 10.30 hertz (depending on the octave of the tones produced), are perceived as even pulsations occurring with varying degrees of clarity over the course of the piece.

I imagine these fundamental frequencies and their related harmonic tones as the elemental components of a moon, and this music as offering a glimpse into its vast lunar-sonic existence.
