New releases last four weeks: Bass

Review: Hexed or vexed, either way Aya sounds pretty pissed off about something. Which is no bad thing. There's a lot to express rage about right now. But that's not really what this is about. Instead, as the blurb explains, this is a record which "confronts the desperation and dysfunction of addiction." No longer "me-less", this is what happens then the lights are turned on and both audience and artist see the real portrait for what it is. And that's pretty hard to define. There are moments here that erupt into niche-bassline levels of unabashed bouncy overbite silliness. At other times, it's freaky deaky broken grunge-electro. Then we descend into sludgy staccato mayhem. Fans of Rainy Miller, Iceboy Violet, and Arca take note - this is comparable, in the sense that it's pretty much incomparable.

Review: Get ready for a wholesome spread as Coco Bryce makes his debut on the cult BXL Underground and feeds us our supper this eve. First up a little liquid refreshment in the form of 'Bubble Tea'. Zesty, punchy and reviving; this 'Soca Tek' vibe is laced with a dizzy array percussion all hitting in harmony or counterpoint. Pure natural energy. Need to line your stomach? Chow down on the techno flavoured 'Tiger Bread'. Rich in all your favourite 4x4 vitamins, this one stamps so hard you might just lose your appetite.

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: You will always have a job second-guessing where The Gaslamp Killer might go next. This time, it is to a new collaborative album with Jason Wool. ANANDA find the pair cooking up 33 minutes of avant-garde experimental jazz underpinned by heavy bass and topped with plenty of sound design madness that calls to mind the likes of Stanley Clark, David Axelrod and Aphex Twin. The synapse firing collage of 'Chaos In The Brain' is a great example of the joys of this record - organic and synthetic, chaotic yet calm. It's a real treat.

Review: Imperieux - or Alper Durmush to use the Bulgarian-raised, Berlin-based producer's real name - is not one to follow the crowd, as his debut CD on the always excelling Macro label testifies. He's clearly versed in a number of electronic sub-sets, from breakbeat to techno and bass music, but the ten tracks here follow very much their own path. Not that it's some way-out-leftfield experiment. Durmush clearly knows how to construct a decent groove - see the gliding opener 'Fo Pio'. Our favourite? Possibly the choppy breaks of 'Almost Had It', or the sheer hypnotics of 'Phase Rotation'. But there's no weak links here, just a producer well versed in the spectrum of dance production and, even more importantly, how to make it work for him.

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: 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: Get ready for some proper breakbeat tackle as Oil Gang reprobate Boylan recruits the troops for a heavyweight apocalyptic 140 BPM showdown. With the likes of Slimzee, Trends, D.O.K, U.S.F and Youngsta all on side, the mood is tense and the textures are rough. Imagine that sci-fi sternness of Virus, that old school rolling breakbeat bass of Koma & Bones or Evil 9 complete with the more modern neck snap abrasion of acts like Former or Coido and you're in the right rave. Mean, gritty and unapologetic.

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: 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.

Review: BertBert's boundary-free TOPO imprint returns with a fascinating body of work from one of his nearest and dearest influences; Windu. A collection honed from hundreds of sketches, grooves and soundscapes written over the last eight years, Juxtapose is a beguiling blend of ambient textures, gritty technoid grooves and thunderous showers of breaks. At points bubbling with aggy rave energy ('Deck 16'), at others entirely disarming and likely to knock you horizontal ('Ti Si Isceljenje'), Windu (which stands for wave is not defined) has a refreshing ability to completely negate DJ formula, arrangement and genre trappings. A debut dispatch built up over years before unleashed into the wild on vinyl, this is a truly unique album.
