Allow Lemonade to reintroduce themselves. On both their ecstasy-spiked self-titled debut and 2010’s Pure Moods EP, the Brooklyn-via-San Francisco trio presented themselves as scatterbrained hedonists. “Neptune,” the first single from the band’s forthcoming LP, Diver, is different. The song is a “Marvin’s Room”-esque vignette of post-party depression, where Callan Clendinen is left to sort out the hints, allegations, and things left unsaid with whoever’s on the other line. Tropical percussion and sleek synth pads lend “Neptune” an expensive-sounding yet fragile feel of a Wham! ballad, but the sound here is very much situated in 2012. The song’s named after the god of the sea, but the immaculate heartbreak of “Neptune” is the sound of Lemonade finally coming up for air. MORE
