Two years after their debut album rewrote the relationship between pop and dance music, swapping deep-house moodiness for EDM bombast and introducing a singer named Sam Smith to the world in the process, Disclosure return with a follow-up that runs even deeper. Slinky beats fuel clubbier cuts like "Jaded" and "Echoes," but the album's heart beats at a slower, woozier tempo, yielding moody R&B highlights featuring The Weeknd, Miguel and newcomers Nao and Kwabs. And Lorde brings smoky presence to "Magnets," balancing the brothers' billowing synths with just the right amount of grit.
