Low Jack (aka Philippe Hallais) is one of the more exciting producers to emerge from the experimental techno community clustered around Parisian labels like In Paradisum and L.I.E.S., a New York transplant. To take rudimentary machine beats and attack them with scouring pads is neither new nor even particularly interesting in and of itself, but what distinguishes Low Jack's work is the way he seems to be groping his way towards his own musical language, one beyond the limits of either noise or techno as conventionally rendered. On his debut album, last year's Garifuna Variations, he twisted archival recordings of Central America's Garifuna people into grimy knots as part of a commission from Paris' Quai Branley Museum. Cut loose from the conceptual framework and institutional ties, Sewing Machine is a far freer album, and a lot more fun.
