Ytterlännäs Gamla Kyrka - Organ rehearsal tape is part of an ongoing musical research where Maria W Horn explores decaying memories of her home area Västernorrland. Following the 2021 release of Stigsjö Kyrka - Organ Rehearsal Tape, these site-specific compositions result from the idea that events and emotions create inherent memories in a building, object or instrument, and that these “traces” or “ghosts” are available to us if we are willing to listen. The pieces on this cassette are arranged and played together with Mats Erlandsson, on the choir organ located in the church room.

Panoptikon is a suite of music for voices and electronics composed in 2020 for an installation in the disbanded Vita Duvan panoptic prison (The White Dove Prison) in Luleå. The work was originally presented as a multichannel sound and light installation where loudspeakers placed in the cells of the prison transmitted the imagined voices of the inmates. In the compositional process, Maria W Horn has tried to imagine how consciousness is affected by the sensory deprivation of the isolation cell, where the only indication of the passing of time was found in cycles of daylight amongst the silence, uncertainty, and solitude.Performing vocals on the album are Sara Parkman, Sara Fors, David Åhlén and Vilhelm Bromander.

The music heard on this album was originally composed as a score for the second half of the film Nico/Nico Crying made by Andy Warhol in 1966. These recordings were made in the last week of 2021 and are essentially live-recordings performed by the composers together in the same room and recorded in a manner reminiscent of the record making process as it was in the late 1960s. The instrumentation used to make the sounds on this album consists of modular synthesis, zither, voice, contaminated field recordings and metal percussion.

The Earthward Arcs cassette contains two pieces dating from 2020 focused on spectral musical exploration in between the realms of the acoustic and the electronic. Starting from small snippets of code - Maria is using the SuperCollider language to create precise sonic frameworks - these algorithmically generated sketches have developed along with Vilhelms unique approach to the double bass - his focus on acoustic details, intonation and timbre.

Stigsjö Kyrka is the first in a series of rehearsal tapes containing recordings of pieces for four handed organ and electronics. The pieces are composed for or adapted to specific organs and the acoustic environments they inhabit. This musical arrangement uses amplified and electronically treated organ in conjunction with a fixed electronic part to create a hybrid instrument with a transformed timbre still anchored in the harmonic language associated with the music traditionally performed on the instrument.

“Turning field recordings into staggering noise vistas, gravelly swells of industrial rhythm, epic subs and gorgeous Eno-esque ambience, the first joint work between Swedish electro-acoustic composers Maria W Horn and Mats Erlandsson, a fellow sound artist and studio assistant at EMS Stockholm, gets some extra special attention on this new 2020 edition.“
Reissued aug 12, 2020 by Boomkat

Nocturne för Maskinhallen is one iteration of a larger number of pieces based on the acoustics in the machine hall at Ställbergs Gruva. The harmonic material consists of the resonant frequencies in the room's reverberation. This harmonic framework has in this particular piece been composed to a sequence of sine waves and recorded when spatialized in the room through a system of multilayered feedback.

Transmutation – the conversion of one element into another – is the overarching principle for this release in which four contemporary artists transform iconic historical texts into sound; through breath and bells, field recordings and strings to the repeating cycles of pure sine waves. “Interlocked Cycles for Sine Waves” is as part of the cassette compilation as a dialogue with the modern mythical figure of Satoshi Nakamoto. “Analogous to an accelerating freeze frame of the innumerable algorithmic trades taking place every second on the global stock exchange; the glacial mounting of both tempo and tension in Horn’s composition slowly reveal the complex tapestry which its seemingly simple and repetitive patterns weave.”

"Where last year’s Kontrapoetik was furious and direct, Epistasis is passionate and exploratory, structured like an ouroboros that in completing its form comes to both an end and a beginning. One depends on the other, the circularity of this mythical figure not so much an instance of unmoving things but of action and reaction, chains of effects whose relationships are anything but linear." - A closer listen

"The album is a mirror of horror, a form of skillfully engineered intensity. I am constantly in doubt whether to be scared and prepare myself for doomsday, or if this might be the sound of liberation. - Passive Agressive"

"Its immediately apparent that rather than being a dry academic chin-stroking sonic art affair or pure nihilistic power electronics record, ‘Diverted Units’ is a celebration of the power and sheer force of high impact sound and its effect on both mind and body" - Norman records

"String instruments are plucked, scraped, played with objects, fed through electronics and it seems that all of this is done at the same time. An excellent record, me thinks, of minimally changing yet massive fields of sound." - Vital weekly
