New releases last four weeks: Dubstep

Review: Following mesmerising Marseilles mutations from the likes of Syqulone, Kabylie Minogue and Lisa More, Cain ? Muchi return to Gros:Oeuvre with their remarkable debut album. A heady tagine of grime, beats, techno, global bass and contemporary electronica with a title that either refers to famed Moroccan popstar or, far more likely, relates to meaning as 'universe', Dounia is a beguiling clash of western electronics and eastern bars, lyrics, and vocal harmonies. Fractured and macabre throughout from the distorted hardcore bass highs of 'J'wadi' to disarming vocal cries of 'Majdouba' this post grime, pre apocalypse opus is a trip from edge to edge.

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.
