Kiran Sande, the shadowy figure pulling the strings behind London electronic outpost Blackest Ever Black, is one of those label bosses who can make a record sound essential through sheer turn of phrase. The debut release by Naaahhh comes with next to zero biographical information—just the promise that he, she, or they hail from “under London,” plus a found photo of a hippy raver, cross-legged and grinning on an Afghan rug, with a half-rolled joint laid out in front of her. Luckily, Sande’s liner-notes make up for some of the gaps in the narrative, promising “sidereal downers for all hardcore ravers” and “paranoid street music meets the cosmic disturbances of musique concrète, the MDMA spine-freeze of isolationism and England’s hidden reverse.” With a billing like that, it’s hard to resist.
