Helena Hauff and F#X get together on a new project for Pan called Black Sites. This is riotous and cerebral club music. The analog artifacts of "Prototype" permutate in tandem with melodic Detroit chords, a pounding rhythm section and a central ascending 303 line. "N313P" maintains the intense pace. Building around competing resonances, the untethered Drexciyan melodies probe, expand and contract to rapturous effect. On white vinyl.
