SBTRKT's early releases were futuristic takes on British two-step garage and bass music, but the masked U.K. producer has moved farther away from those influences with each record. On his second full-length, he twists the bright synths and catchy vocals of his past work into hip-hop: A$AP Ferg contributes a manic, drug-fueled tale to ''Voices in My Head,'' and the instrumental ''Lantern'' is psychedelic trip-hop. The LP also touches on Afro-funk-flavored house (''New Dorp. New York,'' with Vampire Weekend’s Ezra Koenig) and ambient atmospherics. The eclectic sounds are impressive, even if a tighter focus might have hit harder.
