Back catalogue: Techno (Alles)

Review: For "Spectres", a 6-track split release, Buttechno teams up with DJ Speedsick, a Chicago-based artist, famous for his raw and uncompromising approach to sound. Together they explore sonic and textural possibilities of the extreme forms of dancefloor music employing distinct ways of sound manipulation. Buttechno's side features highly saturated textures being torn out, dissected and sewed back together with a wicked use of spectral processing. On the other side, Dj Speedsick, known for reamping his material with guitar amplifiers and cabinets, puts out tracks that bear unique sonic qualities and transform the usual sense of space and distance. The underwordly sounds and high-speed beats presented on this split go beyond the common bounds of dancefloor music, exposing the spectres that dwell between the genres.

Review: Trauma Collective returns to shock your system on their fifth release, which comes courtesy of Spain's Rafael M. Espinosa aka Geistform. The Barcelona-based artist, also known for his exploits under the Univac alias, has crafted a singular style that exists at the interzone of IDM, digital noise and electro and having earned him releases on Pi Electronics, Femur and Hands Productions in recent years.

Espinosa executes four programs in sonic warfare on the Antena EP, all sounding akin to complex bitstream amplification. A multi-level barrage of frequencies play offense on opening cut "Proxima B", which sets the theme for more widescreen pulsations that gash the senses, as heard on the syntax error of "Note Repeat" and building up to a climax on the monochromatic soundstage of "Norc" - a jagged and angular exploration in bass artefacts and static redux.

Since unleashing the austere techno of Birmingham legend Mick Harris (as Monrella) and hometown hero Kwartz on unsuspecting ears, the Madrid-based collective has now ventured into more experimental spheres, as heard on the off-kilter mentalism of ASC's Loop Research and the brooding atmosphere of Makunaimadama's limited cassette release last year. Antena is the logical progression for the label's next chapter, where it continues to push the threshold of electronic music's outer limits.

Review: Club Night Club is a new Brooklyn label born out of an event series, and they're positioning themselves squarely in the leftfield of the contemporary techno scene with a wild EP from the lesser-spotted Herron. The Manchester-based artist has slipped out a few scattered releases over the past six years, from EPs on the meandyou label he helps run, and one big drop for Peder Mannerfelt's label. This fierce return to the fray shows the producer pushing a tough yet supple strain of mutant, stepped techno with soundsystem blood pumping in its veins. It's ludicrously high-end, swimming in needlepoint sound design and yet still rough as hell, and it comes very highly recommended.
