Chicago's own DJ Roc volleys an electrified 2nd album of footwork with 'Practice What U Preach' for scene supporters, Duck N' Cover. Working a perfect balance of sampled soul and technoid Afro-futurism, it weighs up some of his deadliest cuts and jabs in the likes of 'Lowend Unity', named after his 'hood and flush with a mix of pealing sax, droning subs and mercurial synth drops; with the lump-in-throat brilliance of his hyper Jhene Aiko flip, 'The Worst'; and not least the staccato pulses, ricochet rimshots and choking bass pressure of 'I Make Gutta'.
