Aspen Edities News

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.
