Review: INDEX:Records founder and self-styled 'DJ and sound engineer' Conna Haraway finally makes his vinyl bow following a couple of low-key cassette and digital download releases. According to the Sydney-based imprint handling the release, Theory Therapy, the wonderfully titled Spatial Fix was partially inspired by the Glasgow-based artist's 2024 tour of Japan and South Korea. You can hear that in the subtly far eastern melodies and ambient techno style textures of ten-minute opener 'Freon', whose grooves would undoubtedly have impressed the late Andrew Weatherall, and the hushed, semi-abstract, deeply layered wonder of 'Switchback'. Elsewhere, the stretched-out, immersive and meditative '1702' joins the dots between low-tempo ambient techno and dub techno, while 'Patent' is deep, otherworldly and suitably sub-heavy mutant dancehall.

Review: Ensemble Modern and experimental, Berlin-based music composer and sound artist Hainbach come together for Primer, an album sourced from their 2022 Checkpoint concert and reworked in the studio with bassist Paul Cannon. The record transforms their fine live performance into a rich, immersive home listening experience with Hainbach's signature use of nuclear research gear, tape loops and vintage electronics weaving haunting, ever-shifting textures throughout. As such the pieces pulse with a sonic spark that captures the spirit of experimentation and collaboration and is taps into plenty of avant-garde thinking in its approach to drone and ambient.

Review: Big emotions often come in small, intimate packages. Initially at least. Judith Hamann opens her stunning contemporary classical-ambient meditation with the kind of hush that means music and sound creep over you without making themselves instantly known. Before we know it, the transformation - or, perhaps more accurately, transportation - is complete. Using field recording techniques, Hamman augments the electronic harmonies and refrains with au naturel noises, from the hubbub of distant conversation to an asthmatic's whistle, all of which places the plugged-in and synthesised in a very human place. The result is something that feels timeless, as crystalline and clear as it is water-weathered and sepia-hued. The overall affect is mysterious and adventurous, like walking down a serene empty beach only to realise you can't remember which direction you came from.

Review: El Hardwick's sophomore album, Process of Elimination, explores illness as a pathway to personal and anti-capitalist transformation. Rooted in their experience of chronic illness after years of pushing their body beyond its limits, the album reflects Hardwick's journey toward healing through mysticism and natural remedies. Turning away from the need for a formal diagnosis, Hardwick embraced a process of self-rewilding, rejecting capitalism and gender norms to reconnect with their body and the earth. Musically, Process of Elimination combines lush, dubby soundscapes with cosmic experimentation. Tracks like Dual feature sparse synthesiser tones alongside woodwinds and double bass, creating a spacious environment for Hardwick's spoken-word reflections. Collaborations with musicians such as Alex McKenzie and Laura Misch bring a range of organic textures to the album, enhancing its sense of natural exploration. The album shifts between ambient meditations and more rhythmic moments, with highlights like 'Quantology' and the IDM-tinged 'How Do I Know...?' revealing a balance between introspection and forward momentum. Hardwick's process is further mirrored in their personal journey of coming out as trans non-binary, which they describe as another form of elimination, moving beyond binary definitions. Ultimately, Process of Elimination is a powerful reflection on healing, acceptance and the reclaiming of energy, inspired by thinkers like Silvia Federici and Donna Haraway, and enriched by contributions from London-based artists and friends.

Review: Russell Haswell brings Deep Time, marking his sixth release on Diagonal following a productive 2024, which included the 4x12" compilation 13, on top of a UK-wide tour. Deep Time spans a vast influential range, reflecting Haswell's diverse background in computer music, black metal, noise, techno, and improvisation. Deep Time explores all from geopolitical tension to the incomprehensible scale of time itself, drawing sublime inspiration from his solo trips to the Scottish Hebrides and the rock formations glimpsable there. Album highlight 'Unconformity' references James Hutton's geological discovery and its connection to the Earth's history, with typography for the album sleeve designed by MuirMcNeil.

Review: When it comes to hunting the very of best library music cuts out there, De Wolfe's discography is likely the best place to start, and finish. The British music production company were the first to license such music exclusively for film and TV and thus single-handedly popularised the now DJ's favourite genre. Here on this reissue, Aussie producer, musician and double bassist Johnny Hawksworth (one of two famous library musician "hawks", only once removed from the perhaps more eminent Alan Hawkshaw), prizes open both falcon's eyes and auriculars: 'Bite Hard Breaks', the star, makes for an unfathomably cool piece for the playing of seductive games. Unsurprisingly, but with this fact not known to many, this record has been much sampled by hip-hop titans, from Beyonce to Drake to Jay Z to Madlib.

Review: Canadian composer Hecker's movement into scoring for film and television has been a natural progression over the past 25 years and now the artist has perfectly aligned his sound with motion pictures and film. Perhaps not fully intentional by Tim but most fans point to him as an artist whose music evoke emotions that equal the power of what a film could create. Known for his transcendent soundscapes that push ambient music into unclassifiable realms, Hecker collects a series of compositions originally created for projects like Infinity Pool, The North Water, Luzifer and La Tour. While some pieces were left unused in the final productions, their standalone presentation here showcases Hecker's ability to evoke vivid atmospheres. The seven-track EP, released via Kranky, includes the hauntingly beautiful 'Sunset Key Melt', where celestial chimes echo amidst layered, dense melodies. It exemplifies Hecker's knack for crafting spacey, droning soundscapes. Meanwhile, 'Morning' begins as a delicate piano piece before unsettling feedback disrupts its serenity, blending traditional composition with experimental textures. Shards reflects a late-career revelation: Hecker's immersive sound design translates seamlessly to visual storytelling. His work on Arctic psycho-chiller The North Water and supernatural horror Luzifer underscores his ability to merge ice-cold atmospheres with emotional depth. This EP is both eerie and ethereal, showing why Hecker's style is so compelling.

Review: Over his 25-year career, this veteran composer has crafted transcendent soundscapes that resonate with cinematic depth, making his music a perfect fit for storytelling on screen. Shards, a seven-track album released via Kranky, compiles selections from scoring projects like Infinity Pool, The North Water, Luzifer and La Tour. Tim Hecker's journey into film and television scoring feels like a natural evolution of his artistic vision. The haunting 'Sunset Key Melt' features celestial tones and layered textures, creating a spacey ambiance that is sure to impress. In contrast, 'Morning' begins as a serene piano melody, disrupted by unsettling feedback that blurs the line between beauty and unease. Each track balances traditional composition with experimental sound design, resulting in a collection that is both eerie and enchanting. This album reveals how seamlessly Hecker's soundscapes translate to visual narratives and the warm, tactile vinyl experience just seems to underline that even further.

Review: From what we understand about this record, Hualun band member MK had a hand in finishing what was clearly already a beautiful collection of instrumentals. Rubey Hu was polishing off the collection as China finally started emerging from what, from the outside at least, looked like a particularly brutal and unashamedly authoritarian response to the Covid-19 pandemic. A set of serene and incredibly relaxing, playful-leaning piano pieces, MK helped apply various effects and textures, which genuinely elevate what's here. Regardless, though, Rubey's musicianship is inescapable throughout. Eight tracks that feel as though heart and soul have been spilled across the ivories, with additional contributions from another Hualun head, Ding Mao. Really special stuff that will make you want to start exploring Chinese alternative music, if you weren't already.

Review: Trumpeter Chris Ryan Williams and cellist Lester St. Louis form HxH (H by H) are a boundary-pushing electroacoustic duo who work with acoustic instruments and electronics in real-time. Their debut album, released on KMRU's label OFNOT captures their expansive, sculptural sound, and it is one rooted in jazz, noise, classical and Black experimental traditions. Drawing comparisons to Sun Ra or Laurel Halo, their music is fluid, unpredictable and emotionally resonant. Tracks like 'Pyrex Vision' and 'BEACH' showcase a dynamic interplay between form and freedom and are influenced by visual artists like Torkwase Dyson. HxH's sonic world is both daring and intimate and is an ever-shifting architecture of sound.
