Chicago house fixture DJ Heather is arguably one of the city’s top commodities-and for good reason. Her blend of hard-hitting, bass-heavy house fills dancefloors the world over, and she retains an uncompromising underground feeling that conjures up images of dark, humid loft parties. Dancefloor Principles neatly captures her live sets (without the sweat and stale beer, of course), pouring the liquid funk and dark, dubby soul of producers like J.T. Donaldson, Lawnchair Generals and East Coast Boogiemen through the home- or car stereo speakers without missing a beat.
