Drone-y dubstep? Technicolor techno? Heady hip-hop? More like all of the above, along with a couple side orders of we’re-not-quite-sure-what-to-call-that-yet. Like his Werk Discs labelmates Actress, Zomby and Lone, Lukid is part of a post-everything class of wildly promising young producers — the kind of comprehensive beat conductors who actually know the difference between the sample-delic instrumentals of J Dilla and the woofer-wrecking wobble of drum & bass. Which explains why Chord is nearly impossible to pin down, as the triple-pack LP shifts from the brutalized bass lines and smothered hi-hats of “Stripes,” “Saddlebags,” and the rather heavy “Hair of the Dog” to the more melancholic fare of “Makes” and “Child of the Jago,” a dimly lit downtempo track that’s driven by waterlogged synth lines and swampy loops. If you’re into Flying Lotus and other leaders of electronic music’s new school, it doesn’t get much more essential than this.
