Fierce, subtle music, radically strange and unafraid of the deep, but with a killer understanding of rhythm. Lush drum-machine nocturnes, gnarly electronica and glorious flowerings of zoned-out dubspace: an evolutionary music, continuously engaged with experimentation both in the studio and the club. Whether prepared solo, or jointly with his spar Mix Mup, a Kassem Mosse recording is less of a stand-alone creation than the next thrilling installment of an unstoppable groove. True to form, Disclosure dazzlingly extends some of the most mystical, essential dancefloor-rooted music of the last decade, from dusty, dream-state techno on Workshop and Mikrodisko, to frazzled beatdowns on Trilogy Tapes and Nonplus. Pedigree techno and house are the lifeblood of Disclosure, yet with something newly microscopic about them. Its mesmerising juggle of pointillistic percussion, melting-wax chords and fleshy bump’n’grind suggests biological processes at work, as if Mosse has zoomed right into the cellular metabolism ticking away at the core of the music. These textures are woven into some of KM’s richest and most emotionally complex material so far, constantly enlivened by forays into jazz, dub and beyond. Check the farty-bottom, broken-down, steel-pan minimalism of Collapsing Dual Core, just the job for coursing around Detroit in a car at night; and Phoenicia Wireless' dastardly, intricate combination of glowering John Carpenter synths, heavy static and junked consoles on remote, as if the beats are fighting a wave of dirt, soot and fossilisation. The frantic, interstella tarantella of Galaxy Series 7; the wonky bump-and-hustle and heavy-lidded drama of Purple Graphene, to close. Expertly pieced-together and paced, Disclosure brilliantly registers all the self-contained coherence and artistic authority of an album proper, yet shadowed throughout by the open-ended and questing spirit so vital to Mosse’s music. Its intimate enactments of non-closure, and its sense that anything could happen at any moment; its thematic play between excess and incompleteness, babble and tongue-tied stutter, and-you-don't-stop grooving and entropy, wobble and the pause-button. Trash and ready in a spiffy Bankhead sleeve, too. Double bim. Bim, bim.
