Open Wide, Booth readers; Calvin Harris is about to cram his latest single right down your throat. OK, on second thought, that sounds kinda wrong, and you can probably get away with listening to this jam with your mouth closed, so long as your ears are ready to experience some absolutely ferocious bass. Here, the Scottish DJ and producer's synth boardwork slowly builds to a pulse-pounding chorus as guest spitter Big Sean mixes recollections of past breakups and relationship woes with miscellaneous freakiness. As a bonus for the rap nerds, Harris seasons his beat with that iconic Funky President “Hey!” An unknown director's action-packed visuals accompany the cut. Like what you're hearing? Well, you're in luck; pre-order the headliner's Motion LP in advance of its November 4, release, and you'll receive Open Wide as an instant download!
