New releases last two weeks: Leftfield

Review: Billow Observatory returns to the fully ambient realms of their 2012 debut with a deeply introspective, percussion-free release that drifts through spectral soundscapes. Created by Jason Kolb and Jonas Munk, the duo's transatlantic collaboration has matured across four full-length albums marked by precision and emotional depth. Here, abandoning traditional structure, the album instead looks to harness the power of chance and randomness with shimmering guitar textures that crackle and dissolve like dust in water. It evokes a world slightly out of sync that is brooding, haunting and beautifully immersive while underlining their place as masters of refined, atmospheric ambient music.

Review: Talk about appropriate names. There's something about Helen Island that sounds as though it has been cast adrift, washed up, and left to establish its own thing. The Parisian enigma's work feels ghostly, haunted by a past that has vanished into the ocean mist. Whether they'll ever be reunited is the real question, but mystery is the joy here. Whether it's at the uptempo, synth pop hued 'Hot Zone Regular Day', or the weird and wonderful psyche-electronica-field style 'Forever Starts Today', breathy samples on 'Indivisibl' or the innocent contemporary classical-cum-ambient plucked strings and keys of 'Restless Lovers' and 'Gore Lore', the whole thing is a strange and beguiling ride through the outer reaches of popular music.

Review: Berlin-based producer JakoJako aka Sibel Kocer's debut album for Mute - after appearances on a stream of leading German labels including Tresor - is described as a distillation of ideas that she's been exploring for many years. In reality, that means working on a minimal set up, away from the computer while restricting herself to just a Eurorack and a Waldorf Iridium Core, in the search for spontaneity. She found it, for sure, as the results - recorded in Vietnam during the Tet Lunar New Year celebrations - are a feast of glistening arpeggios and lush modular textures, stripped back but full of expression and personality. 'Ghi-ta' will appeal to fans of vintage perky ambient productions the Pete Namlook/Mixmaster Morris collaboration Dreamfish, while 'Gio' has a touch of Tangerine Dream's classic widescreen sensibilities. Bold tones, bold debut.

Review: Annea Lockwood is a pioneering New Zealand-born experimental composer who returns to Black Truffle with her third release for the label. Although she is now the handsome age of 85, Lockwood continues to explore new sound sources and collaborate with a range of performers and 'On Fractured Ground' features recordings made with Pedro Rebelo and Georgios Varoutsos while using Belfast's "peace lines" as resonant instruments that deeply evoke the dark history of the Troubles. 'Skin Resonance' is a collaboration with Vanessa Tomlinson that explores the bass drum's sonic properties while infusing them with elemental textures. Both pieces showcase Lockwood's reflective, meditative approach and make for another significant entry into her creative story.

Review: In 1984, Gary Numan launched Numa Records and started a new phase in his career with the release of Berserker. This album introduced a harder-edged digital sound into his canon while maintaining the analogue textures of his earlier work. It's a testament to the fact that Numan's creative evolution never stopped and blends both personal and fictional narratives into haunting tracks like 'My Dying Machine,' 'This Is New Love' and 'Berserker.' The remastered double vinyl edition includes the original album with bonus tracks that add extra perspective to this pivotal period in his career.

Review: Parus is a Belarusian ethno-ambient project blending pagan songs with modern soundscapes and Zara is their debut album. Led by ethnographer and folk singer Hanna Silivonchyk, the record features traditional Belarusian songs in various dialects, all accompanied by synths and field recordings crafted by Anton Anishchanka. The tracks were gathered during ethnographic expeditions across Belarusian national parks, and songs like 'Soniejka' and the title cut offer intimate reflections on life, love and mythology. It connects to the past while maintaining a deep personal edge that makes Zara a fascinating exploration of Belarusian culture.
