Review: B12's 1993 debut album, Electro-Soma, has long been regarded as one of intelligent dance music's "must-have releases". Offering a decidedly intergalactic blend of otherworldly techno, ambient and deep space electronica, it remains a brilliant piece of work. Here, Warp Records give it the reissue treatment, packaging the peerless original album with a second disc of early B12 rarities and hard-to-find cuts recorded during the same period. There's naturally plenty to admire on this bonus disc, from the shimmering electro bustle of "Transient Pathways" and Motor City futurism of "Debris", to the intoxicating ambient brilliance of "Go With The Hiss". That this material is every bit as good as the tracks included on Electro-Soma is testament to the (then) duo's rarely matched brilliance.

Review: In 1979, Cabaret Voltaire - then consisting of all three founder members, Richard H. Kirk, Stephen Mallinder and Chris Watson - recorded a soundtrack for an experimental film "for two projectors" by Babeth Mondini. 40 years on, that soundtrack has finally been given a release. It's similar in tone to some of the Sheffield experimentalists' other soundtrack work from the period, offering discordant, unsettling and otherworldly sound collages that fuse heavily modified and processed instrumental parts (guitar, bass, drums, clarinet, saxophone) with tape loops, sampled dialogue and the band's ever-present electronic tones. Whether you're an obsessive Cabs fan or not, it's well worth a listen. This is, after all, a slice of previously hidden musical history.

Review: The arrival of a new Cabaret Voltaire album - the first since 1994 according to our records - should excite all those who hold the work of the pioneering Sheffield outfit dear. It's now a solo project from Richard H Kirk (he decided to keep the name after parting company with Stephen Mallinder in the late '90s), but the distinctive stylistic ticks remain (think paranoid sonic textures, metallic percussion hits, clear dub influences, plentiful spoken word samples, curious electronic noises and nods towards the industrial funk, EBM and post-punk). Naturally it's not as ground-breaking as Kirk and company's work in the '70s and '80s, but it is undeniably a Cabaret Voltaire album - and one that subtly updates the Cabs' particular brand of dense, dancefloor-ready paranoia for a new century.

Review: Having taken time out to travel the world and experience new things (including psychedelic substances in California), John Hopkins planned to make Singularity, his ninth album, "a sonic ecosystem that starts and ends on the same note". He soon got frustrated by these limitations, so instead just laid down a fluid and hazy album that combines his usual luscious, ambient electronics with a variety of sparse, heavy and off-kilter rhythms. While undeniably laidback in parts, the album also boasts a number of foreboding techno workouts and uses a wider palette of instrumental sounds than we've come to expect (including some fine strings and his own intricate piano playing). The resultant set is rather impressive, all told, and while not quite a "sonic ecosystem", it's certainly an enjoyable journey.

Review: The irrepressible Past Inside The Present is back with the second in a trilogy of tape loop experiments from T.R. Jordan. This is the limited and hand-numbered CD format and is another cohesive piece of this three-suite puzzle. All of the music was made by the same materials and methods and was all made in "a concentrated period of inspired experimentation with no energy wasted." The artist calls it a form of "musical composting" and the music is full of a sense of musical grace and elegance, peaceful pads and sonic versions of pastoral scenes like flowing rivers and mossy rocks under beautiful wispy clouds.

Review: Experimental musician Leyland Kirby has been skirting round the edges of electronic music since the tail end of the '90s, delivering curious concept albums under a dizzying variety of pseudonyms (The Caretaker, The Stranger, Billy Ray Cyrix, Butcher Claws and Bored in Columbia, amongst many others). Here he dons his familiar V/VM alias for a discordant trip into drone territory supposedly inspired by fading memories of the last throes of early '90s outdoor raves. In truth, there's little in the music - a typically hissing, dystopian fusion of murky textures and becalmed electronic tones - to justify the concept, but it matters little. Kirby is a master at creating vaguely spooky, industrial-influenced soundscapes, and The Death of a Rave (A Partial Flashback) only enhances his reputation.

Review: What does it mean To Belong? Cynthia Bernard aka. Marine Eyes only begins to scratch the surface of this question on her latest ambient record (yet leaps a great deal forward in wrestling with it nonetheless), following up her prior effort 'Chamomile' with a distinctly beauteous fortnight of forenoon drones, all of which spur the realization that "belonging is everywhere and nowhere". Belonging is indeed a kind of ephemeral longing of being than can only ever be partly grasped, attained. Through its looping washes of warmed, brackish, padded backwash - not to mention its many bass-undergirded angel choirs - the likes of 'Timeshifting', 'Bridges' and 'Mended Own' stand out as such revelatory highlights, all contributing to an incredible album of sonic diaristic reflection, in which every sound sticks out clearly yet plays its proper part in a humble, rose-smelling gestalt.

Review: Analogue synth spooks rejoice, Pye Corner Audio is back with further explorations of the sweet spot between nostalgic fuzz and circuit-borne futurism. Ghost Box is a spiritual home for Martin Jenkins' flagship project, and he continues to edge out the scope of the Pye Corner sound without derailing the fundamental atmosphere. On The Endless Echo, warm, pulsing melodics set to eerie keys abound, and there's a fine balance between gorgeous ambient atmospheric pieces and sinewy, danceable rhythms, but Jenkins manages to sound fresh and inspired even while reliably holding true to the overall project aesthetic.
