New releases last two 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: 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: 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: 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.
