New releases last two weeks: Minimal/Tech House

Review: A punctual reissue of a rare Eye 4 Sound tech-acid house party starter from 2004, this Repeat version of Dexter's 'Paradox' stays faithful to one of many EPs in UK artist Mat Royall's regal flush of technical itches to last from 01 to 06, spread across labels like Beat Code, Random House and, in more recent years, Real Deal and Bosh Records. 'Paradox' is subset by the fun-loving 'Ychtm Acid' on the B-side, and while we can't claim to be so clever as to be able to decode this standout track's strange titular acronym, we can vouch for the sickness of its eccentric percussions and atmosphere, a fine case of what we call "mood design".

Review: Not to be confused with the heavy Dutch electro hero of the same name (he of Klakson Records fame), Dexter was the early-to-mid 2000s alias of UK tech-house producer Matt Royall. Sushitech Records recently released a retrospective of his work, Past Moves, and now German label Repeat has decided to reissue 2004's Size Counts EP. A-side 'Break It Down' is deep, druggy, chuggy and pleasingly off-kilter, with delay-laden spoken word snippets and echoing hand percussion hits rising above a driving bassline and hypnotic, locked-in drums. The pace and intensity increases on flipside 'Once Again', a kind of Hipp-E & Halo style West Coast tech-house workout rich in trippy female vocal snippets, ghostly chords and dubby bass.

Review: Neil E and Big City Bill's latest doubles as the second offering from Spincycle, yet another a split 7" single on 180g vinyl. The twins' journey began two decades ago high up in an unnamed mountain range, where they met, after which they descended onto the city in search of purpose. Thus spake Zarathustra: down below, they toiled away in dimly lit garages, decoding mysterious symbols cast on walls by home-gaffed fluorescent lights. At first, their work seemed like madness, but there comes a time in every madman's life when toil leads to breakthrough. Thus were sowed the two fine harvests you hear here: 'Dry Rub', with its tugging taut sound design, and 'The BBV', a mistier firmament of altitudinal unknowns. No need to map out the terrain first - just give in to your ears.

Review: Rick 8 is the techno alias of Italy's Riccardo Falsini, and here he revives the pioneering spirit of his iconic Interactive Test label with this early gem, which offers an essential slice of trance, techno and progressive house history. Known for reshaping genre boundaries, the label was a beacon of innovation, as this EP shows. Each track is a potent club tool, designed for transcendental dancefloor moments and sonic ascension from the chunky tribalism of 'Hypernotes Velocity' to the standout remix of 'C'Mon' by Sound Metaphors affiliate Trent, who injects progressive firepower. 'Born To Sinthetize' is a deeper, spiritual sound with flashy synth work married to loose drum loops.
