Hot from the first electric note, dream-pop Danish duo Sweet Tempest commands your attention immediately. Their new track Empty Box is a soul slayer — all sweet rhymes and heart pings, layered with echoed whimsy and badda-bings. It’s got that magical formula that songs you can’t quit have, a sound you can drink a thousand times and not get any drunker on it than that optimal level of arousal that makes you put it on repeat. Play it once and you’ll be hooked. Trust me, this is your new favorite drug.
