So far in 2009, Ostgut Tonträger has charted a course favoring harder, more aggressive sounds than in previous years. As the label arm of Berlin’s preeminent Berghain club, whose name has become synonymous with dark and uncompromising techno, this isn’t entirely surprising. Prominent resident DJs/producers Marcel Dettmann and Ben Klock have also seen their stock skyrocket since the label launched in late 2005, furthering the case for harder stuff. And while a discography notched with several releases from Prosumer & Murat Tepeli, 12″s from MyMy and Âme, and the Shut Up and Dance! Updated compilation evinces diverse tastes, one wonders if Ostgut Ton’s recent focus portends a broader shift. If commissioning an EP and album from Luke Slater’s ferocious Planetary Assault Systems project was the tipping point, the “Deuce EP,” a collaborative effort from Dettmann and Shed, lays bare how astringent and foreboding the path ahead may be.
