New releases last eight weeks: Deep Dubstep

Review: Peddling heavy, sweet subs that ooze out of the scoops like syrup, Portuguese low end maestro 3WA makes his debut on Infernal Sounds with four utterly stinking brouhahas. 'Scavenger' starts the commotion on a deep but stern note and things get more and more twisted throughout the EP... 'Minotaur' grunts and growls with a over-sized toxic bassline while 'Mutt's flips from cosmic and percussive to straight-up deranged. Last but not least 'Wandering' finishes the EP on a last lingering groan. Refreshingly woozy.

Review: DJRum's career has blossomed in recent times, in no small part thanks to his mind-mangling and frequently thrill-a-minute DJ sets. Unusually given his prolific work-rate earlier in his career, the much-admired producer has not released much new music of late; in fact, this mini-album for Fabric offshoot Houndstooth marks his first 100% fresh release for five years. It's predictably impressive, with highlights including the twisted TB-303 trickery, bombastic sub-bass and polyrhythmic post-dubstep UK bass beats of 'Codex', the high-octane modular techno insanity of 'Crawl', the spaced-out and dubbed-out, Autechre-ish IDM weirdness of 'Frekm (Part 1)', and the deconstructed breakbeats, psychoactive electronics and metallic effects of 'Frekm (Part 2)'.

Review: Ever since launching his Echoboy project on the label, Moonshine has played a key role in Adam Kupec's output. Rising up from his Riddim Tuffa roots with a disarming, deep dark vibe, he's made his sonic statement clear since 'Jahova' in 22 and 'Fire' in 23. Now back with 'Rasta We Rasta', his signature seems to gleam off the wax. Digital but warm and resonant. Dancefloor but laced with a little soul. Highlights are the ominous boom of the Danny Red featured title track and the tricky cymbals and shiny finish of 'Horns Dub'.

Review: The connection between ZamZam and Feel Free Hi Fi was sparked by Bristolian Neek out in Portland and lead to an immediate bond forged over a shared sound and DIY ethos. Inspired by early digi-era dancehall and UK dub, the duo crafts a sound here that honours tradition while venturing into bold, idiosyncratic territory. It comes on their own Digital Sting label and opens with 'Voyageur' which is a mix of cinematic atmospherics with haunting synths that evoke wild and mythic landscapes. 'Underground' pays tribute to the spirit of DIY underground music and captures the struggle to preserve both nature and the essence of basement gigs in today's shifting cultural landscape.

Review: Liverpool Dubstep Heads invite Russian artist Ninety over for some low-end fun and these four tracks are the result of their adventures. As with many of his previous tracks, Ninety errs on the side of trippy across the EP with strange off-grid flurries and psychedelic twists throughout. Highlights include the wavey sheen and sparkle of 'Rouz', the pinched staccato drama of 'Fear Suppression' and the all-out theatrical tension of the title track. Hunt and go hard!

Review: Dubstep and garage pushers Hotflush make a surefooted return, welcoming Perth producer Odd Occasion to their roster with an al dente next-gen garage cookoff. This 'Jukebox' offers six choices to the discerning listener, though you'd be hard-pressed to find a pub owner who'll take them on in toto - unless the landlords happen to be real heads, that is! All's well that this is a machine with niche appeal, with its formal calculations and dark contusions tempting fans of all things bass-led. Though the record begins on a volatile yet minimal note, the A3 'Simple' takes a glassy dubstep turn, virtifying the mix with hollow sound design and a stealthy grime vocal sample. The B-side betrays a sacrifice of genre focus, with 'Salt' bringing brutal trade zone techno via experimental trap sound design, and 'Tape' progressing through tender zithers, which help uptick the mix to reach a snappy folktronic finish.

Review: The return of Sorrow, characteristically with a gracefully morose new six-tracker, 'Unrequited'. "How can I forgive?" goes the rheum-smeared vocal sample opening out the Bristolian artist's new opener 'Monologue', after which amnestic choral lines follow like heavenly flights, singing thee to thy rest. Many a temporal restretching of the 2-step grief-garage paradigm follow, as on the slo-mo dancehall of 'Fallen Angel', the pan-fluting, blossom treeing dubstep of 'Unrequited', and an unlikely future downtempo saudade, 'Hedron'. It's nice to hear Sorrow back in action; without his continued presence, we might otherwise drown our own in other, less musical liquids.

Review: Beatrice M's amusingly entitled Bait label has in fact become exactly that - very desirable to those who know. Its latest is a four tracker that serves as a taster of a forthcoming digital album by Trois-Quarts Taxi System. Behind the moniker is Eloi Petillon, a versatile producer, DJ and live act who has a knack for blurring genre lines. On this one, they mix up elements of dubstep, techno and d&b into soundscapes that are cerebral, hypnotic and psychedelic. Each one is made from futuristic sound design, field recordings and intricate polyrhythms: 'Metamorphism' warped, linear, deft and brilliant deep techno. 'Coma' is more busy, 'Fraction' has wispy synths and a sparse soundscape and 'Spectre' is a fizzy, skeletal sound that tickles the brain.
