Back catalogue: Dubstep

Review: Garage powerhouse Zed Bias is back with more old school garage brilliance with the new single 'Shell Them Again' featuring the vocals of Yung Saber and Brakeman. The original has plenty of retro signifiers from the low-end wobble to the withering synth effects, plus crisp hits and jostling drums. After the dub mix comes a remix from Zed himself alongside Safire which is much more dirty and raw. The beats are broken up so the track takes on a dubstep quality as the low-end oscillations bring the weight and drums hit with more force. Finally, the acappella closes out this fresh 12" on IFG.

Review: Woof! Hyperdub bring together two of the most recognisable and enigmatic artists of recent times on this 10", as Zomby and Burial square down ahead of the former's new album for the label. Zomby's Ultra LP is undoubtedly one of this year's most anticipated albums and "Sweetz" suggests it may be a very moody affair indeed. Whilst rooted in UK dance, Zomby and Burial do look elsewhere for inspiration too. Just under seven minutes long, "Sweetz" veers through various sub-heavy soundscapes with intermittent rhythmic patters and a distinctive looped vocal sample whose pitch changes with dramatic effect.

Review: Remarkably surreal club reconstructions from Uruguayan ur-producer Lechuga Zafiro. 'Desde los oidos de un sapo' ('From The Ears Of A Toad') is a truly elastic entanglement of designed sound refit for the floor, though we'd not be surprised if a private laboratory set aside for the safe containment and study of sonic bio-anomalies would hope to acquire this one too. Zafiro flexes his hylid hamstrings on this wriggling wet lurch through post-Baile sonics and field recorded club jamborees, emphasising the naturalistically percussive and fretfully textured. Basing his musical identity on field recordings of hard materials - metal, wood, rock, glass - as well as, somehow, animal tissue - from toads, birds, sea lions and pigs (let's hope they were at least taxidermied first) - these seven cochlear leapfrogs make for a highly exploratory sonic escape; Zafiro dares to define the next applicative generation of sound design for the dance.
