It's hard to believe the group behind the garish EDM hit "#SELFIE" could grow into something more solid and significant, but that's just what happens to the Chainsmokers on the Bouquet EP, a more indie-flavored effort with some touches that are as elegant as the cover art. "Roses" is a stuttering, swaying beauty with the apt choice of ROZES delivering the vocals, then "New York City" comes on with soft, nocturnal deep house touches that are nowhere near that "#SELFIE" slam. "Waterbed" is closest to that early hit, although a cuter and quirkier version as if imagined by the Super Mario team at Nintendo. This diverse and free EP gives up more questions than it does answers, so think of them as clever teases, and then wonder if the Chainsmokers are EDM pranksters with an artful touch, or the forefathers of elevated glitzy indie bro pop EDM, or something to that effect.
