Following the release of founder Powell's recent, acclaimed Club Music EP, London label Diagonal continue their swerve into caustic dancefloor territory with the debut pair of 12" releases from Bronze Teeth. Titled O. Unilateralis and A Waif's Rent, their extended technoid grooves perfectly match the project's name — they're tough, hard-edged and intricately sculpted for tensile strength and visceral impact.Traces of the sounds that feed into Bronze Teeth can be heard in the duo's individual projects. Dominic Butler is one-third of Factory Floor, the London-based trio renowned for their wiry, dynamic live shows; his modular electronics are an integral component in that band's devastating cocktails of Morse code electronic blips, drum and guitar. Richard Smith meanwhile, records as L/F/D/M, and debuted with a scintillating clutch of acid tracks on Optimo Music in 2013. Bronze Teeth offers them free rein to explore their own interests in sound, and in particular the potential for chaotic interaction between metallic programmed rhythm and the fleshy pulse of the human body."The organic development of the music and the themes and focus of the project were discussed in the artspeak hangover of our art school days," say the duo. "The rhythms and cycles of life, the persistence of nature. Conversations would sway between description of tone, texture and line within a visual context, to a translation into music, through trying to keep everything loose, pushing against the rigidity of the sequencer, and through running with chance and exploiting errors. Nature, printmaking and the futile attempt to escape pattern all collide."So on these two debut 12"s, Bronze Teeth pair brain-pummeling repetition and steely mechanical funk with a raw, untamed sensibility. On O. Unilateralis’ sprawling opener 'Tapeworm' and the glassy club noise of 'Acetone' and 'Glass Tooth', they appear to be skirting along the edge of control, with their machines wrestling dominance back from their users and sending sparks ricocheting through the mix. For all its monochrome battery, this isn't lo-fi music, nor is it retrogressive. The ghosts of acid house and skull-shredding free party techno lurk in this machine, but they're refracted through a modernist sensibility and a keen ear for sound sculpture: edifices honed from diamond-hard tones and reinforced glass, all wrung from a sprawl of patched-together gear. Second 12" A Waif's Rent opens harder still, with 'Albion Pressure' ushered in by a cloud of distortion and teeming particulate matter. It gathers momentum and fury as it plays, scuttling forward like a column of army ants. On the flipside 'Cut Bronze and 'Tephra' hew stark funk from woody drums and static blitz, tellingly akin in mood and effect to recent Diagonal releases from Powell and Russell Haswell.
