[ bass/dance ]

Addison Groove (a.k.a.: Headhunter; rhythmically felicitous birthname: Tony Williams) made his name as an early adopter, within the U.K. bass-music scene, of the coarse aesthetics and turbo-charged kinetics of Chicago's Footwork music — with, most notably, his addictively blunt 2010 debut track "Footcrab." Transistor Rhythm, his first full-length under the moniker (released on Modeselektor's 50 Weapons label), finds Williams' productions growing a good deal more refined, weaving in elements of jazz and twinkly eyed electro alongside plenty of genial floor-friendly thumping. Not too refined, mind you — he enlists the filthy mouth of our boy Spank Rock to keep his old-school ghetto house homages suitably gutter-minded. And it's a safe bet he's arrived on our shores with plenty of brutal, frill-free bangers in his bag.
