New releases last four weeks: Bass

Review: Patrick Conway is back on ESP Institute for a third time and the returns are as brilliant as the first two outings with plenty of emotional depth on display. Opener 'Loss' sets a melancholic tone with a repeating high piano note guiding a poignant chord progression, angelic voices and a modulating synth all sinking you in. That contrasts with a gritty rhythm section made from corroded dancehall elements all bathed in saturation for added authenticity. On the B-side, 'Silencio' explores negative space and rhythmic dialogue using anthemic synth stabs to unify the more meandering melodies. When chaos and order synchronise with force like this, there is fun to be had.

Review: Let's get a little slimy this season... Hooversound regular DEFT invites Manni Dee over for some superb slo-mo sludge. All flexing around the 100 mark, there's some serious swagger to be savoured across the five cuts. Highlights include the incessant insectoid buzzes of 'Busy Bee', the sudden jolt of euphoria of 'Charged' and the gut-wrenching twistedness of 'Creep'. Elsewhere 'Witchlead' pushes the drama buttons while 'Greedy' ends on the slowest tip of all as we dip down to 90BPM and get mangled to some faraway cries. Swampy is as swampy does.

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 can be hard work keeping up with the myriad of different labels that Burnski aka Constant Sound aka Instinct heads up. This one leans more into UK garage and welcomes Main Phase for another succulent selection here. 'Gotta Maintain' kicks off with a nice dusty garage sound that will get your lip curled, and then Buckley brings broken beat rework with dubbed-out low ends. 'Soul Mirror' is a clean, bouncy sound with a cool synth breeze and 'Breather' brings some olds school references - the raga vocals, the bleeping synths and the monstrous bass. Brilliantly filthy.

Review: Mucha, AKA Amanda Butterworth presents a stunning double header for Frequency Domain's tenth birthday release. But when up against one of the most thoughtful, precise, yet loose and rave inducing producers in the history of synthesisers, there was only ever going to be one opening point being made here. Surgeon's remix is typically essential for any techno fan. So while the original 'Skin' is this patient, rhythmic but beat-less slice of post- (or pre-)club stuff, full of ecstasy moods and comedown overtures, Surgeon's take refocuses us on the repetitive vocal patterns and slaps a wonderful compelling broken kick underneath to create a proper dancefloor builder. B-side 'You Make Me Go Under' goes for a neo-Bjork style IDM leaning piece, which then gets a moody, apocalyptic Datassette cut to top off an exceptionally strong package. Buy it. Buy it now.

Review: Sub Basics is back on his own fledgling label Temple of Sound - but under a new alias. As Tommy Basics he leads into a fresh house sound but still serves it up with plenty of his textbook bass-heavy low ends. 'Latitude' is a bubbly groover with dusty drums and fleshy basslines that get you moving and warmed up. 'Longitude' is even deeper, with smeared dub chords and woody percussive hits peppering the laid-back and inviting groove. Two stylish sounds from this versatile producer.

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.

Review: Upsammy's ever mutating, morphing sound seems to melt before your very ears on this new body of work. A distinct beaty twang, and even drum & bass, comes into the mix as the Dutch maverick takes us on a unique trip. Highlights of her navigations include the deconstructed d&b of 'Relict' and the hypnotising chimes and shimmers of the title track which feels like a trip to a temple in Tibet while cruising the back pocket of an automaton. Powerfully mesmerising; minimal in dynamic, maximum in feels. Don't sleep on this one.
