Earlier this month, German DJ Helena Hauff released her debut EP for Actress' always-reliable Werkdiscs imprint, Actio Reactio. Hauff's wasting no time out of the gate, as her next release will be a collaboration with the unpronouncable fellow German producer F#X as the ominous-sounding moniker Black Sites; their debut EP, Prototype, drops in Europe this Friday, August 23, via PAN (it's out August 30 in the States), and this is the thick, transfixingly unwieldy ten-minute title track, which extends some of the wilder sounds found on "Actio Reactio".
