There's a entrancing undertow that pulls you into Airling's subterranean utopia. It conveys itself in supple grooves and a heartfelt voice that lingers long after the track disappears. Songs like "Move Me", "Give Me All You Got" and "Not a Fighter" show mastery of dance-floor dynamics, hip-hop drum patterns and ambient headspace-a similar environment inhabited by bands like The xx and Massive Attack. Hard to Sleep, Easy to Dream shows body and mind working overtime in joyous lockstep.
