After six EPs, the duo delivers a star-studded full-length. Toggling between brooding, seductive electro-pop ("Neck and Neck (feat. Dragonette”) and rambunctious hip-hop (“Already Done (feat. Ghetts)”, Northern Lights never lingers in a mood for too long. But dubstep-pop hybrids like “Too Young (feat. Rivers Cuomo & Pusha T)” make the whole project feel seamless.
