In August, London-born producer Roska dropped a UK-funky-meets-UK-garage track entitled "BFF". To keep the buzz going around the new single, he's drafted in Stateside turntablist and Hot Mom USA boss Shiftee to work his magic on the original. Plunging the track deep underwater, Shiftee crafts a bubbling, popping and silky smooth club track with a well-selected Missy sample thrown in from left field. And because it's Shiftee, and he doesn't do anything by half measures, he's also recorded a DJ routine to go with it. Make sure you watch that here.
