Review: Basel-based experimental labels Amenthia Recordings and A Walking Contradiction join forces for their first collaborative release here in the form of the Flash Crash/Hack Crash EP. Both labels are known for pushing boundaries within their close-knit creative circles and this one features Agonis' heavy stepper and Konduku's whirlpool of low frequencies on the Amenthia side, while Lemont continues the low-end, tripped-out vibe. Varuna represents A Walking Contradiction and delivers swampy, slow-motion sounds in their signature style. This release embodies both labels' commitment to daring, unconventional electronic sounds.

Review: Leipzig based Riotvan, run by Peter Invasion and Panthera Krause, welcomes Kalexis and Paulor for this collaborative four track that mines techno's deepest depths. 'Going Through The Void' is a moody and slow motion opener that rides on an undulating bassline with plenty of ambient pads for company. 'Energy' is more edgy, a stomper with fractured vocals and wonky synths that builds a darker mood. On the flipside there is the brilliantly unhinged and unusual melodies of 'Lashes' which sounds like a marching band on acid and 'Magnetic' closes down with haunting low ends and spooky pads.

Review: KANZ's artist alias, when reversed, becomes ZNAK, meaning "SIGN" in Bulgarian. He hails from Lyulin, a district known for breeding either crime or art, and thankfully Kaloyan embodies the latter. This outing on MELMAK is opened with '25% Personality (with Dickie)' which is deep and atmospheric dub techno. 'Low Orbit' is just as deep but more driving with some pad laced beauty up top, 'Trench Music' then brings frosty Berlin dub techno vibes, 'Dub Tool A' has conscious vocal mutterings and 'Splais' is a slow motion gem for late night contemplation. 'Kopriva (Opa Kanz Rerub)' is a spine-tingling closer with angelic vocals.

Review: UK producer Inigo Kennedy - also known as Seducer, Tomito Satori and Helki Torsnum - comes up with a pair of techno tracks that positively glisten with luxuriant melody and a beautiful musicality that's rare to ape in this - or indeed any - scene. 'RackSpace 2' and 'Dewdrops' both glide with serene ease, the melodies weaving away in the back seat of the track but never threatening to overwhlelm the atmosphere. The latter is definitely operating in a spacier sphere, with the reverbs and delays working overtime, but both are nicely restrained takes on techno that nevertheless paint vivid sonic pictures.

Review: Kop-Z reveals that he first encountered the term 'A Non-Equilibrium Thermodynamic System' in a book costing L2 in a Manchester junk shop. It is a term to describe humans as systems constantly battling entropy and the world's challenges to survive. "But we're also systems that work together, creating art and music," he reflects, appreciating the contrast between opposites like day and night, love and hate. His work merges autobiographical field recordings, looped vinyl and childhood video games with kinetic programming systems that are all influenced by jungle, footwork, noise, rave, post-punk and reggae. The result is a rich fabric of sound that blends human experience with machine chaos.

Review: It's hard to argue with how much work Koreless, AKA Lewis Roberts, has put into things. Born in Bangor, Wales, but based in Glasgow - currently the most exciting UK city for electronic music production - it took a decade from his debut EP, 4D, to his first album, during which time he participated in the sorely-missed Red Bull Music Academy programme, collaborated with Sampha, performed on Boiler Room TV, embedded himself within the Young Turks camp, wrote with FKA Twigs, and was credited by David Byrne. That's a lot to unpack, so while the bubble wrap is unloaded let's skip to right here, right now. Deceltica is a particularly Koreless collection of tracks, from the opening warning sirens and haunting melodic chimes of 'Seven', to the robot breaks of the title number, and 'Drumhell''s near-reprise of the opening track, a kind of outro to that intro, it's all very good. Then you get fellow Welshman and resident at Manchester's beloved Bakk Heia party, Jorg Kunning, proving why he's up there with the most technically brilliant beat makers.

Review: If you've not heard 'Skyscrapers' yet, where have you been? First released digitally last year and accompanied by more remixes than we can count, the track is arguably Nina Kraviz's most accessible, radio-friendly release to date - a potential crossover anthem that's as cool as it is catchy. Now finally available on vinyl via this single-sided seven-inch, 'Skyscrapers' is a prime piece of what Kraftwerk would have called 'techno-pop', with the much-loved Russian producer's sweet vocals rising above a bed of ultra-crunchy, snare-heavy machine drums, dreamy Chris Lowe chords, gaseous pads and ear-catching lead lines. It's basically synth-pop, but it's classy and sonically deep enough to please all but the angriest underground techno purists.

Review: Since delivering his debut album on PNN a decade ago, Matt Kent AKA Matt Karmil has proved adept at adapting the club-focused sound of his EPs to the long-playing format - as his inspired and wonderfully atmospheric sets for Idle Hands and Smalltown Supersound prove. He continues this notable run of form on this Studio Barnhus released set, crowding ultra-deep, dusty grooves in opaque chords, cut-up sample snippets, lo-fi crackle, hazy ambient textures and nods towards a myriad of ear-pleasing electronic styles and sounds. Highlights are plentiful, with our picks being the dubby, mind-altering late-night hypnotism of 'Still Something There' and the becalmed, meditative ambient deepness of superb closing cut '15 Mins' (which, confusingly, is just 13 minutes long).

Review: Layer is the new label from Berlin techno favourite Berghain for the music released by its residents. Ben Klock is one of the most celebrated of those and here he links up with Fadi Mohem for an album that eschews his famous techno sounds in favour of a new blend of IDM, ambient and experimental sounds. 'Layer One' comes on double vinyl and opens with 'Ultimate (feat Coby Set)' which is an atmospheric opener with icy synths and sparse landscapes, then 'Escape Valley' explores kinetic rhythms and glitchy synths, 'The Vanishing' is another exploration of a distant corner of the cosmos and 'The Machine' brings more cinematic and evocative electronic designs.

Review: You might say the clue is in the name, but as well as bearing a nice selection of differently cut beat action, this double album from French/Syrian producer Ahmad Qatrami aka Konalgad on New York's Dance Data label, is also a nicely cerebral affair jammed with celestial adventures for mind as well as feet. It refuses to get stuck in any stylistic rut, from the cloud-like ambience of 'REM' to the brooding bass and dubby stepping of 'Subzero Experiment' and the simmering shimmer of 'Dots To Dots', half digi-dub thump and half subtly filtered junglist trimmings, it keeps on giving something new right to the end. Konalgad apparently translates as "the universe of tomorrow" in Arabic, and this artist definitely has a bright future to match his already quite impressive track record.

Review: The seminal musicians who have graced King Biscuit Time on US radio are too many to count, but who's complaining when so much gold material can be dusted down and given a fresh pressing. They surely don't come more momentous than this - German electronic pioneers Kraftwerk captured in 1975 as they were in the midst of progressing from their warm, organic kosmische roots towards the game-changing synthesis they're eternally treasured for. 'Autobahn' is of course the big hit here, stretching out over the A side as it should, but don't overlook the wonderful 'Kometenmelodie' and two-part 'Morgenspaziergang', all demonstrating Schneider, Hutter et al as the extraordinary visionaries they were.

Review: Everyone's favourite robotic pioneers have embraced the art of the remix plenty over their lengthy career. As well as taking fresh approaches to their own material, they've invited others to mess with the legacy of one of the most important electronic acts of all time. It's no mean feat to remix a Kraftwerk track, but as such the roll call on this compilation is reliably heavyweight. As well as their own 'Kling Klang' remixes of tracks like 'Robotnik' and 'Expo 2000', you can find legends like DJ Rolando, Orbital, Francois K and Hot Chip tackling classic and some lesser known tracks across three slabs of wax.
