Nick Parkin's experimental music is about place and space, and Entropolis textures a glassy, utopian city with a hidden, organic world below. Like Brian Eno, Parkin uses keyboards and percussion to craft an ambient bubble of faux found sound, constructed to feel closed and precise as opposed to the wide open plains of a band like Zoviet France. Parkin plays his own source material for sampling which detaches Entropolis and locates it on its own island of machinery. Referents are constructed as the album progresses, as opposed to being embedded in pop culture like DJ Shadow and DJ Qbert's scratch samples. But Parkin's compositions are not for fans of the new age, nature music, or elevator tunes. From the discordant clank and grind of the title track to the repetition of "Vault" (which sounds eerily like a calculated swamp full of human-made frogs and insects), Entropolis is difficult music that requires the attention and energy of a committed listener if it's not to annoy.
